Rubber Accelerator FAQ
Q: What is the recommended dosage of Rubber Accelerator in rubber compounds?
A: The typical dosage ranges from 0.5-2.0 phr (parts per hundred rubber) depending on the rubber type and desired curing characteristics. For natural rubber, we recommend starting with 1.0-1.5 phr, while synthetic rubbers may require slightly higher doses of 1.5-2.0 phr.
Q: How does Rubber Accelerator affect the scorch time of rubber compounds?
A: Rubber Accelerator is designed to provide an optimal balance between processing safety and curing speed. Our formulation delivers excellent scorch safety at processing temperatures while rapidly accelerating vulcanization at curing temperatures, typically providing 10-15% longer scorch time compared to conventional accelerators at equivalent curing rates.
Q: Can Rubber Accelerator be used in food-contact rubber applications?
A: Certain grades of our Rubber Accelerator meet FDA 21 CFR 177.2600 requirements for rubber articles intended for repeated use in contact with food. Please consult our technical datasheets or contact our support team for specific grade recommendations based on your application requirements.
