Lubricant G60 is a PVC processing lubricant grade used to control friction between PVC compounds, processing equipment, and finished surfaces. In practical terms, it helps PVC materials process more smoothly, reduces sticking and torque, and supports a more consistent surface finish when the formulation and processing conditions are correctly matched. However, “G60” is a commercial grade name rather than a universal chemical standard, so I recommend reviewing the supplier’s technical data sheet before treating it as a direct replacement for another lubricant.
At Shitong, I position Lubricant G60 for buyers who need a dependable internal or external lubricant option for rigid and semi-rigid PVC applications. The correct selection depends on resin type, stabilizer system, filler loading, equipment, processing temperature, and the required balance between fusion and lubrication. A laboratory or production trial remains the most reliable way to confirm suitability.
Lubricant G60 is generally supplied as a solid additive for PVC compounding and processing. Its function is to modify the friction and melt-flow behavior of the compound during mixing, calendering, extrusion, injection molding, or related operations. Depending on its chemistry and formulation design, a grade may provide mainly internal lubrication, mainly external lubrication, or a balanced combination of both effects.
Internal lubricants help reduce friction within the PVC melt and can influence fusion behavior, melt homogeneity, and processing torque. External lubricants primarily reduce adhesion between the PVC compound and hot metal surfaces, which can help limit plate-out, sticking, and die buildup when properly balanced. Because the commercial name alone does not fully identify the chemistry, I advise buyers to confirm composition, recommended dosage, softening or melting behavior, and compatibility with the complete formulation.
The main purpose of Lubricant G60 is to improve process control rather than simply make PVC “slippery.” A suitable lubricant can help the compound move through equipment with more predictable friction, support smoother demolding or extrusion, and influence the final appearance of profiles, pipes, sheets, or molded parts. These benefits depend on the correct dosage and on maintaining a suitable balance between lubrication and fusion.
Rigid PVC profiles, window components, conduits, and pipes commonly require a controlled lubricant balance to achieve acceptable fusion, dimensional stability, and surface quality. A lubricant that is too external may delay fusion or create surface defects, while insufficient lubrication can increase torque, sticking, or equipment wear. I recommend evaluating G60 with the actual resin, calcium carbonate level, stabilizer system, and extrusion profile used in production.
In sheets and panels, lubrication can affect melt release, surface appearance, roll behavior, and the tendency of material to adhere to processing surfaces. The ideal grade depends on whether the product requires a high-gloss, matte, embossed, or printed surface. Buyers should examine not only processing performance but also possible effects on printability, welding, coating, and downstream forming.
For injection molding, a lubricant may influence mold release, filling behavior, weld-line appearance, and cycle consistency. The suitable dosage must be determined together with injection temperature, mold design, residence time, and the thermal stability of the PVC compound. A formulation that works in extrusion should not automatically be transferred to injection molding without a controlled trial.
PVC lubricants may be based on different chemical families, including fatty acid derivatives, esters, waxes, metal soaps, and other specialty materials. Each family can show different melting behavior, migration tendency, external release performance, and influence on fusion. G60 should therefore be treated as a defined supplier grade whose technical identity must be confirmed through its TDS and, where necessary, safety documentation.
For internal and external lubrication, I focus on the performance relationship rather than the product name alone. An internal lubricant may improve melt flow but can affect fusion time, while an external lubricant may improve release but create plate-out if overdosed. In many PVC formulations, the best result comes from a balanced lubrication package instead of relying on one additive to solve every processing issue.
Before purchasing Lubricant G60, I suggest comparing the following specifications and test information. The values should be taken from the current supplier documentation because commercial grades can differ between manufacturers and production lots.

| Specification or property | Why it matters | What I recommend confirming |
|---|---|---|
| Appearance and physical form | Affects feeding, blending, storage, and handling | Powder, flake, bead, color, odor, and packaging condition |
| Melting or softening range | Influences release, dispersion, and processing response | Test method, stated range, and batch consistency |
| Acid value, saponification value, or equivalent chemistry data | Helps identify chemical behavior and formulation compatibility | Applicable analytical method and specification limits |
| Recommended dosage | Provides a starting point for laboratory and production trials | Application-specific range rather than a generic number |
| Moisture, ash, and purity-related data | Can affect dispersion, appearance, and consistency | Test method, maximum limits, and quality-control frequency |
As a practical starting point, PVC lubricant screening may begin around 0.2–2.0 parts per hundred resin, often written as phr, but this is not a universal recommendation for Lubricant G60. The actual level can vary significantly with resin K-value, filler content, stabilizer type, equipment, and desired fusion behavior. I would use this range only for structured trials and would rely on torque, fusion, surface, and release results before finalizing the formulation.
First, identify whether the problem is high torque, metal sticking, slow fusion, rough surface, die buildup, poor release, or inconsistent feeding. Different symptoms may require different lubrication adjustments, and adding more lubricant is not always the correct solution. I recommend recording the current formulation, processing temperature, screw speed, output, torque, and visible defects before changing the additive.
Next, match the product to extrusion, injection molding, calendering, or another process. PVC processing zones may commonly operate around 160–200°C, but the appropriate range depends on the compound, equipment, residence time, and product design. The lubricant must remain compatible with the thermal and shear history of the application rather than being selected from temperature alone.
Use the same resin and additive package while changing only the lubricant grade or dosage wherever possible. Evaluate fusion time, torque, melt pressure, surface appearance, die buildup, plate-out, and finished-product performance. For a B2B qualification, I also recommend checking results across more than one batch so that a promising laboratory result is supported by repeatable production behavior.
One frequent mistake is assuming that every product called G60 has the same chemistry and performance. Another is selecting the lowest price without comparing active content, packaging, consistency, technical support, and actual dosage efficiency. Buyers should also avoid changing lubricant level without considering the complete PVC formulation, because a lubricant adjustment can affect fusion, surface quality, and downstream operations.
A second mistake is requesting only a product name and price. For a reliable purchasing decision, I recommend requesting a TDS, SDS where applicable, standard packaging details, shelf-life guidance, batch-control information, sample availability, and the supplier’s recommended application range. These documents help the purchasing, quality, and formulation teams evaluate the product using the same criteria.
At Shitong, I support Lubricant G60 sourcing by helping buyers clarify the intended PVC application, processing method, required packaging, and trial objectives. I can discuss whether the material is being considered for internal lubrication, external lubrication, or a balanced role in the formulation. This application-first approach is more useful than offering a grade without understanding the production conditions.
For qualified inquiries, I can help organize product documentation, sample discussions, packaging options, and export communication. Buyers should provide the target application, current lubricant or additive system, approximate monthly demand, destination market, and any required quality parameters. With this information, the commercial and technical evaluation can be more focused and reduce unnecessary trial-and-error.
Lubricant G60 can be a suitable option when you need better friction control, release behavior, and processing consistency in PVC products, but the product name alone is not enough to confirm compatibility. I recommend defining the processing issue, reviewing the supplier’s specifications, testing the grade in the complete formulation, and checking repeatability before approving it for regular production. This process provides a stronger basis for both technical and purchasing decisions.
If you are evaluating Lubricant G60 for PVC pipes, profiles, sheets, panels, or molded components, contact Shitong with your application and target requirements. I can help you review the relevant product information, discuss sample and packaging options, and prepare a practical quotation for your intended volume and destination.
