Technological service
1. It has the “cloning” composite heat stabilizer!
2. It can provide the technologies concerning melting stearate, composite stabilizer, polyethylene wax, aluminate coupling agent and borate ester coupling agent.
The materials are compiled according to knowledge mastered by us at present and only for reference! We do not offer any guarantee. We reserve the right to change product parameters within the scope of technological progress or product development. Since we can not control the processing conditions and coordination raw materials in a wide range, the user has to first test its applicability before normal production.
