Applications：TPPD is mainly used for antioxidantRD of the CR, NR, BR, SBR and latex, protection of ozone, oxygen aging is good, also can inhibit copper and manganese pollution, especially suitable for protective CR released chloride to the fiber materia damage during the period of aging . This product is easy to disperse, and can be added rubber directly, also can make into aqueousdispersion inject latex. And when this product is used for CR, if using in common with antiager ODA, best heat resistant performance, also can reduce the plasticity of unvulcanized CR, Reduce rolling shrinkage, and thus help to adjust the size of the semi-finished products. Mainly used in the manufacture of wire and cable, tires, v-shaped belt, seals, tape and light industrial goods.
Package：Kraft paper bags or paper barrel. 25 kg/bag (barrel).
Storage：Should be stored in a cool, dry, well ventilated place, packaged products should avoid direct sunlight.
Instructions: Can provide different purity products according to customer requirements; The product packaging can be adjusted according to customer's requirements.
