Rubber joint difficult to process

Reason: 1. The tearing strength of the product is too good (such as high tensile adhesive). This difficult processing performance is that the edge can not be torn off. 2. The strength of the product is too poor, showing that the edge is very brittle, will tear the product together.

Solution: 1. If you can't tear it, you have to adjust the formula, fill in the mix and reduce the shrinkage. 2. If it is torn, then a.Reduce mold temperature, shorten sulfur time b.Reduce the amount of curing agent c.Adjust the formula to increase the strength of the compound
