G60 internal lubricant

‌Brand‌: WSD CHEMICAL
‌Product Name‌: G60 PVC internal lubricant

1. Product Profile

G60 is a high-performance, odorless white powder internal lubricant specially developed for rigid and flexible PVC processing. As a fatty alcohol dicarboxylic ester compound, it shows excellent compatibility with PVC resin and other polymer systems, effectively improving melt plasticization uniformity and processing fluidity. Compared with traditional lubricants, G60 provides more stable internal lubrication performance, reduces processing torque, and significantly enhances finished product surface quality and mechanical properties.

3. Key Features & Benefits

Promotes uniform melt plasticization and reduces extrusion and calendering torque

Significantly improves PVC melt flowability and welding strength

Enhances impact resistance and surface finish of finished products

Low volatility and excellent thermal stability, less fume during high-temperature processing

Good compatibility with PVC stabilizers, processing aids, fillers and pigments

No negative impact on formulation transparency and color stability

Low migration performance, avoiding surface blooming and precipitation issues

4. Recommended Applications

PVC Profiles & Panels

Greatly improves melt fluidity during high-speed extrusion, ensures uniform wall thickness of complex sections, and optimizes surface smoothness.

PVC Pipes & Fittings

Reduces internal friction of PVC molecules, shortens plasticizing time, and improves production efficiency and dimensional stability.

SPC Flooring & WPC Products

Matches high-filler systems, improves mixing and dispersion effects, and avoids surface defects such as flow marks.

PVC Transparent Sheets & Films

Provides mild internal lubrication without damaging transparency, suitable for food-contact and packaging-grade PVC products.

PVC Cable Compounds & Granulation

Stabilizes melt rheology, reduces shear heat generation, and improves granulation continuity.

Other Engineering Plastics

Also suitable for PC, PBT, PET, PPO and PPS processing as a high-temperature compatible lubricant.

5. Usage Reference

• Recommended addition dosage: 0.5–1.5 phr in most rigid PVC formulations

• For special high-filler or high-speed processing systems, maximum dosage can be adjusted up to 3–5 phr after small-scale testing

• Suggested to add together with PVC resin and fillers during high-speed mixing to ensure uniform dispersion

• Can be used with external lubricants such as paraffin wax, polyethylene wax and ester wax for balanced internal and external lubrication performance

6. Packaging & Storage

• Standard packaging: 25kg per bag or customized packaging options

• Store in cool, dry and shaded warehouse, storage temperature below 40 °C

• Seal bags after opening to avoid moisture absorption and contamination

• Keep away from strong oxidizing substances and strong acids

• Under proper conditions, the shelf life can reach more than 12 months
