Struggling with cell collapse and brittle cracking in high-speed PVC foam board extrusion? FINE-ADD explains how high-molecular ACR processing aids and CPE 135A impact modifiers improve melt strength, eliminate cell collapse and boost impact toughness.

FINE-ADD launches upgraded technical guidelines for rigid PVC and CPVC extrusion optimization. High-stability CPE 135A solves pipe brittle cracking, while high-performance ACR eliminates foam cell collapse for PVC foam board and WPC extrusion.

Weifang Fine New Material Co., Ltd. expands global supply of high-purity Magnesium Chloride Hexahydrate (MgCl2·6H2O, CAS 7791-18-6) for industrial applications including Sorel cement, water treatment, and de-icing.

Discover practical formulation strategies to prevent cell collapse, eliminate voids, and boost impact toughness in high-speed PVC foam board extrusion using high-molecular-weight ACR and CPE 135A.

Acrylic Processing Aids (ACR) are high-molecular-weight acrylic copolymers engineered to accelerate PVC gelation, enhance melt elasticity, and prevent thermal degradation during high-speed extrusion. Incorporating high-purity ACR eliminates common surface defects like melt fracture, stabilizes wall thickness in rigid pipes, and prevents cell collapse in PVC foam boards and WPC composites.

This technical article explores how combining High-Stability CPE 135A and High-Molecular Weight Acrylic Processing Aids (ACR) from FINE-ADD resolves critical foam sheet extrusion defects, such as cell collapse, surface roughness, and edge brittleness, while optimizing melt rheology and maintaining low costs.
