FAQs
Q1: What is a transparent filler masterbatch?
A transparent filler masterbatch is a polymer additive in granular form, designed to be mixed with base plastics like PP or PE. It contains a transparent filler (such as calcium carbonate or silica) and a carrier resin, typically in a 4–10% ratio. This masterbatch enhances the mechanical strength, thermal stability, dimensional stability, and weather resistance of plastics, while maintaining their transparency. It also helps reduce production costs by partially replacing more expensive base resin.
Q2: Which materials can it be used with?
It is suitable for PE, PP, and works well in extrusion, injection molding, and film blowing.
Q3: How much should I add?
The recommended dosage is 4–10%, depending on the desired balance between transparency and cost reduction.
Q4: Will it affect optical or mechanical performance?
No significant impact when used correctly. The ultra-fine fillers and optimized carrier resin maintain optical clarity and mechanical strength.
Q5: Is it suitable for food-contact applications?
Yes, food-grade options are available and can meet relevant regulatory standards.
Q6: Can RongFeng customize the product?
Yes, RongFeng offers custom transparent filler masterbatch formulations to match your base resin, production process, and transparency requirements.
