The academic term for whitening rubber products is also known as spraying frost, which often occurs after the rubber product is vulcanized and left to stand for a period of time, and the surface appears to be covered with white dust. But in reality, it is the precipitation of rubber compounding agent that forms frost spray.

For the whitening phenomenon of rubber products, our company's R&D personnel have found that the common reasons can be divided into several categories: improper formula design, improper process operation, fluctuations in raw material quality, poor storage conditions, rubber aging, etc.

Since we know the various reasons, we need to grasp the various processes of making products well in order to produce better quality products. If such products were to be produced, our rubber product companies should scrap all the products and strive to provide customers with every quality qualified product.
