Cost-Effective Filler for Rubber Goods
Quartz Powder for Rubber is an economic functional filler. It is made from crystalline quartz through crushing and grading. Unlike high-surface-area silica, it offers good flow and easy processing. In natural and synthetic rubber, this powder raises the hardness, rigidity, and abrasion resistance without using too much mixing energy. We have 25 years of history in the silica powder industry. We understand the rubber sector's needs very well. Every batch of Quartz Powder for Rubber is checked for particle size and iron content. There are no harmful metal impurities.
Better Compression Set and Lower Reject Rates
A rubber seal maker told us about the benefits of using our product. After they started using product, their parts had much better compression set resistance. Their reject rate dropped by nearly 8%. This is a clear sign that choosing the right filler matters. Our Quartz Powder for Rubber is now exported to rubber product makers in Southeast Asia and the Middle East. They all value the quality and the cost savings we offer.

Wide Scope and Custom Options
Quartz Powder for Rubber serves many rubber applications. In seals and gaskets, it boosts hardness and stability. This improves compression set resistance. In conveyor belts and hoses, it increases abrasion and cut resistance. For shoe soles and industrial rollers, it enhances physical properties while keeping processing easy. We can adjust the particle size for your hardness targets and process needs. We also offer a high-purity pickled version. The minimum order is 1 ton. We welcome you to send samples for testing.
