A Versatile Filler for Plastic Modification
Quartz Filler for Plastics is a multifunctional filler for the plastics industry. It is made from high-purity crystalline quartz. We use fine grinding and precision grading. This gives the filler high hardness, low thermal expansion, and good chemical stability. Compared to organic fillers, our product has clear advantages in improving rigidity, dimensional stability, and heat resistance. It is especially suitable for engineering plastics and functional modified plastics.
Reliable Supply for Plastics Compounders
Our customers include many plastics compounders who make automotive parts, electronic housings, and precision mechanical parts. They choose our Quartz Filler for Plastics not just for the performance. They also value our stable supply capability. Our annual capacity of 20,000 tons and flexible scheduling across 6 semi-automated lines ensure we meet your delivery needs. Our service team will provide technical support when you first use our product. We help you optimize your process parameters. This ensures our product gives you the best modification results in your injection or extrusion process.

Wide Applications and Custom Solutions
Quartz Filler for Plastics serves many plastic applications. In nylon (PA6, PA66) modification, it raises the rigidity and heat deflection temperature. This is especially useful for automotive engine parts that face high heat and mechanical loads. In polyester engineering plastics (PBT, PET), it improves dimensional stability and wear resistance. This is common for electronic connectors and relay housings. In polyolefins (PP, PE), it increases surface hardness and scratch resistance. We can customize the particle size for your specific resin and process. The minimum order is 1 ton.
