|---|
| Polypropylene HJ40XI is a nucleated homopolymer with good antistatic properties. This product has high crystallization temperature allowing for cost efficient production based on short molding cycles, gives balanced physical properties including high stiffness, has isotropic & balanced shrinkage resulting in less warpage & potential for pigment leveling, and has good opticals in thin walled molded articles & fresh part appearance due to reduced yellowing. APPLICATIONS : Injection moulding&& |
