What are the factors that are brittle in the production of silicone tube?
In recent times, a discussion was found in the forum. The problem is that there is no one in the silicone tube production.
The process of it, especially when high temperature stripping, easy to brittle tear. But the plastic material is very high. Below
What are the factors that cause the discussion.
Silicone tube products may have the following reasons:
1.
2 high sulfur curing temperature
The 3 little high reinforcement filler formula
4 curing system is not very reasonable
There are 2 kinds of solutions to the silicone tube products:
1 adjust the curing time and temperature
2 adjust the formulation of the curing system, reinforcing system, adding internal release agent
In short, the temperature of high polymer movement is intense, the rubber material heat of the molecular chain is still in motion, so it is easy to appear when stress concentration
Split. Is the hot tear strength difference temperature has dropped down, the performance will be up immediately! It is just after vulcanization Chaimo, production
Products are easy to damage, and other aspects of the problem.
May be multiplied of curing agent, and curing time and temperature are still the original conditions, which leads to rubber in the curing process of sulfur
(aging) and become brittle. In the past, it was like this, in the summer when the curing agent volatile, require a number of curing agent, adjust
The whole good curing condition. But in the fall, when the winter curing agent volatile, or with the same conditions do, guide
In the case of a brittle, sulfur. It is best to adjust the conditions of curing, reducing the temperature of sulfide, look at the.
