The unstable shrinkage of rubber floor mats will lead to the quality of products.
The rub mat has excellent elasticity, excellent cold resistance, air tightness and water resistance, and is harmless to human body; and that rub mat is beautiful in appearance, and has the effects of anti-skid, anti-collision, shock prevention and scratch prevention.precisely because gaming mouse pad manufacturer The rapid development of, so also brought new opportunities to the industry. https://fldrubber.com
When the finished rubber floor mat is molded, it can’t be eliminated because of the cohesion of the elastomer when it is limited by large pressure. When it is molded and separated from the mold, it usually shortens very unsteadily (the shortening rate of rubber is different because of different kinds of rubber), and it takes a period of time to relax and be stable. Therefore, at the beginning of a rubber finished product planning, no matter the formula or the mold, it is necessary to carefully calculate and cooperate. If not, the finished product scale will be unstable and the product quality will be caused.
Rubber belongs to hot-melt thermosetting elastomer, while plastic belongs to hot-melt cold-setting. Because the main body of sulfide is different, the temperature scale of rubber molding and curing also has a proper distance, which may even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber finished products need to be appropriately adjusted at any time, if not, the difference in the quality of finished products can occur.
