Q: How can cracking or brittle failure during injection molding be resolved?

A: We offer formulation adjustments to enhance toughness and reduce internal stress, alongside recommendations for optimized injection molding processing parameters.

 

Q: Do the products hold relevant industry certifications?

A: Our materials meet industry standards such as UL flame retardancy, ISO medical compliance, automotive specifications, weather resistance, and antistatic properties. We provide comprehensive physical property reports and test certificates to satisfy market entry requirements for sectors including home appliances, automotive, medical, and new energy.

 

Q: Are the materials suitable for injection molding and extrusion?

A: All modified pellets are designed with flow characteristics compatible with standard injection molding machines and extruders. They offer stable molding, low shrinkage, and resistance to delamination or cracking, making them suitable for manufacturing housings, structural components, optical parts, sheets, and more.
