PP/PE Anti-Shrinkage Masterbatch

Core Product Value:

- Improve the shrinkage and deformation issues of PP/PE injection-molded products
- Improve the dimensional stability of thick-walled parts to ≥95%
- Adding 1-3% ratio does not affect the material properties
- Reduce surface dents to improve appearance quality
- Suitable for injection molding of complex structural parts

Mechanism of Action and Technical Characteristics

- By reducing the friction coefficient between melt molecules
- Promote uniform melt shrinkage and crystallization
- Control the volume shrinkage rate during cooling
- Maintain the mechanical properties and thermal stability of the substrate
- Good compatibility with various PP/PE substrates
- White granules facilitate production control

Product Technical Parameters

Typical scenarios

- Thin-walled large flat injection molded parts (turnover boxes, pallets)
- Structural parts with reinforcement ribs (automotive interior parts)
- Thick-walled container products (barrels, boxes)
- Precision engineering parts (gears, bearing housings)
- Home appliance casings (washing machine panels, air conditioner casings)
- Outdoor equipment (garden tool casing)

User Guide

1. Mixed process: directly injection molded after premixing with raw materials
2. Barrel temperature: 5-10℃ higher than the melting point of the base material
3. Injection Pressure: Reduce by 5-10% to decrease internal stress
4. Holding time: Extend by 10-15% to improve effectiveness
5. Mold temperature: It is recommended to be 40-60℃.
