Manual operating silicone / silicon rtv2

Manual operating silicone also called manual mold silicone is mainly used for model design. It also belongs to mould making silicone rubber. There are three differences between manual operating silicone and mould making silicone. Firstly, manual mold silicone is relatively cheaper. Secondly, its reduplication which will be 5-10 times is less than mould making silicone. Then, it is applicable to make molds of simple pattern products, toys, alloy car and not suitable for making molds for mass production. The manual operating silicone used most in the market is generally two-component curing type silicone rubber, generally referred to RTV-2. Today, I will introduce the manual operating silicone/silicon rtv2 to you.   Features of manual operating silicone/silicon rtv2: 1. Low viscosity, good fluidity, and easy to operation. 2. Low shrinkage, no deformation, and stable product size. 3. Small quantities of mold replication, model design and so on. 4. Good elasticity, high temperature resistance and used repeatedly after molding.     The distinction of different model mainly added different types and amount of filler and additive into the raw silicone rubber. The reduplication of manual mold silicone ranges from three to twenty or thirty times. Silicone rubber is divided into two components, one group is silicone materials, another group is curing agent. Taking manual operating silicone of Hong Ye Jie as an example, next I will make a brief introduction on the performance parameters of manual mold silicone. 　　 Recommended model of manual operating silicone/silicon rtv2: Model 540 570 Color White White Hardness(shore A) 40±2 52±2 Viscosity(mPa.s) 15000±2000 11000±2000 Tensile strength(MPa) ≥2.8 ≥2.4 Tear-strength(kN/m) 7±2 5±2 Elongation (%) 150 190 Mix ratio (%) 2~3 2~3 Working time(mins) 30~40 30~40 Curing time(hrs) 3-5 hrs(25℃) 3-5 hrs(25℃)   We can find manual operating silicone has nine performance parameters from the table. Below I will do a simple description for a few of them: 1. Color: The basic color is white. in fact, different colors are available according to customer's specific requirements, which will not produce any effect on the other parameters. 2. Hardness: The hardness of the silicone rubber ranges from 10 to 80 Shore A. This range can be exceeded for particular request. 3. Viscosity: Viscosity mainly refers to the ability of liquid itself preventing the liquid flow in fluid mechanics, which is the force of molecules from the microscopic point. 4. Elongation: It is usually referred to the percentage compared to the original length when the sample is fracture. 5. Mix ratio: Different types of catalyst are available according to customer's specific requirements. And the ratio of curing agent can be adjusted according to the operating temperature.   Shenzhen Hong Ye Jie Technology Co., Ltd. is the manual operating silicone/silicon rtv2 manufacturer.
