To understand the advantages of liquid silicone mobile phone case, we must first understand the liquid silicone material. In fact, liquid silicone is no stranger to us. The baby's nipple is made of li......
2020-01-13Although LSRs do not shrink in the mold, they often shrink by 2.5% -3% after demolding and cooling. Exactly how much it shrinks depends to some extent on the formulation of the compound. However, from......
2020-01-10Long-term storage of the mixed silica gel will make the molecular structure of the mixed silica gel, and it will be difficult to open the mixture with vulcanizing agent. The main reason i......
2020-01-10Causes: Impurity of white carbon black, which contains high temperature reaction or ultraviolet discoloring substances, causing yellowing; small molecules left over from high temperature ......
2020-01-10The demoldability during the vulcanization of the rubber is a key indicator for directly judging whether the compounded silica gel can be used. It is not easy to demold the adhesive film and thermal t......
2020-01-10The main reason: the white carbon black on the market is more than ten yuan per kilogram of mixed rubber filled with precipitation method white carbon black, the pH itself is alkaline and contains fre......
2020-01-101. High power LED packaging silicone products are classified according to curing conditions: they can be divided into high temperature curing type silicone rubber and room temperature curing type LED ......
2020-01-09The accelerator can improve the activation performance, so that the blooming problem of the accelerator can be effectively controlled, so as not to affect the physical properties and stability of the ......
2020-01-09In order to increase the vulcanization speed, there are generally two methods: first, increasing the temperature, and then increasing the amount of accelerator or switching to super-accelerators; for ......
2020-01-09The curing time is set according to the thickness of the product and the operating requirements. Because the thermal conductivity of rubber is very poor. The thicker the product, the longer the curing......
2020-01-09The vulcanization temperature depends on the type of rubber. For example, the best vulcanization temperature for natural rubber is 145-148 degrees, the best vulcanization temperature for styrene butad......
2020-01-09Good electrical performance Optimized electrical properties of ceramicized silicone rubber—the volume resistivity before sintering is not less than 1015Ω • cm. As the sintering temperature increases,......
2020-01-08Halogen-free, low smoke, low toxicity, self-extinguishing, environmental protection Ceramicized silicone rubber can achieve the flame retardant self-extinguishing effect without adding a halogen flam......
2020-01-08Has a certain strength and good thermal shock resistance The sintered body after ceramization is relatively hard, there is a ceramic sound when percussed, and it has a certain flexural strength and c......
2020-01-08When the rubber material containing the inorganic filler is exposed to the flame, the rubber is degraded or burned, and the inorganic residue or ash with less strength is left after the degradation or......
