Use rate is extremely high.

The important raw material of rubber is the production of wear-resistant hydraulic seals, seals for hydraulic oil resistant, high temperature resistant hydraulic seals, corrosion resistant hydraulic sealing parts, acid and alkali resistant hydraulic seals, chemical resistant hydraulic seals, oxidation resistant hydraulic seals and other rubber products, but for application in with the requirement of O - ring, join with agent is different and need from the hydraulic seal pieces of various economic and technical indicators of each component proportion data point of view, this is the rubber formulation, for example, hose, belt, rubber sealing parts, rubber shoes belonging to model product, adhesive, adhesive tape and belongs to non - model products. Different parts of each product, the technical indicators used different, the cost of the formula is different. So the economic value of the formula is also very important.

In the same formula, the necessary advanced process elements, such as: curing conditions, process points and economic benefits, and the final production of the O type circle are closely related. So, in the past a lot of rubber formula, but the ratio of materials, if not reached the technical level and technical conditions, it can not be a complete formula.

ine rubber generally used in two sections and sulfur, a temperature optional 170-180 DEG C, cure chooses to 20-23 degrees, according to the needs of technology can be selected in the range of 4-24h.

   According to the end of the hydraulic O type of the ring is not the same functional requirements, the use of rubber formula is not the same as the curing system.According to the end of the hydraulic O type of the ring is not the same functional requirements, the use of rubber formula is not the same as the curing system.And according to the practical vulcanization system to select the corresponding curing temperature. General sulfur curing system, the curing temperature selection range 130-160 DEG C, according to the specific requirements by the use of promoter activity temperature and the product of physical machinery function to judge.

   Promoter activity of temperature low or hydraulic O-ring needs high strength, low stretch should force and hardness, curing temperature can be selected was lower, so generated more polysulfide crosslinks; promoter active temperature higher or product demand high modulus should force and hardness, low elongation, curing temperature should choose higher so generated more sulfur crosslinks.
