Thickening temperature, good strength, high heat resistance,The amount of waste is small, usually only accounts for 2%-5% of the total amount of used materials. The actual amount of material loss also depends on the shape, size and complexity of the molded products. 

Suitable for SMC/BMC production process, used in electrical, automotive and construction fields, adding 9262, 9282 and other low shrinkage agents, SMC/BMC products with standard and low shrinkage can be manufactured
