Silicone rubber use in medicine

Silicone rubber use in medicine will have a more promising future. Condensation type silicone rubber foam is a hydroxy-terminated silicone rubber as the base material, the foaming agent is a hydroxyl silicone oil, a vinyl platinum complex catalyst (heated catalyst dibutyltin dilaurate), in curing the foamed sponge-like elastic body made of a perforated at room temperature. To improve the quality of the foam also adding some other components, such as those containing silicone, so that the curing process to produce more gas; improve the texture and to reduce foam density. Join diphenylsilandiol not only to control the foam structure, but also to control the rubber viscosity increases during storage, but the amount is not too much, otherwise it will affect the electrical properties of the foam. In order to improve the physical and mechanical properties of the foam, a transparent silicone rubber may also be added. The catalyst complexes of chloroplatinic acid in an amount of vinyl not be too easy to operate, and may otherwise cause the operation is not conducive to an increase in viscosity; insufficient when the amount of catalyst, curing is incomplete, tacky surface of the foam, not elastic well, with a soft and plastic, intensity difference. Foam is liquid silicone rubber before vulcanization, suitable for potting material. After curing the foam at long-term use -60-159 ℃, after 150 ℃, 72hour old, or a 60 to 70 ℃ ten ten times using alternating hot and cold, still maintaining the original properties of the foam. Since the silicone rubber foam having a high thermal stability, good insulation resistance, insulation, moisture resistance, shock resistance, especially at high frequency shock resistance, and therefore it is an ideal lightweight packaging materials. For a variety of electronic components, equipment, instruments, instrument flying body can play quot wheels, moisture, shock, quot quot three anti-corrosion protective effect. But can also do the insulation sandwich filler material and salt spray atmosphere of floating materials and sealing materials. Silicone rubber foam padding in medicine but also as orthopedic, repair and re-clothing materials.

The silicone industry prospects

Silicone industry prospects analysis is in the historical continuing development of the silicone industry present situation, the present situation of demand and supply, competition, economic operation, the downstream industry development, market demand depending on the analysis of the downstream industry, around the silicone industry for the future development trends, market capacity, competition, and subdivide the downstream market demand is analyzed, with this device rapid increase of the silicone industry initiated a policy of by the top rated special silica gel in the bulk synthesis of silica gel, become one of the largest varieties of silica gel dosage. Market prospect at home and abroad can also be very big, the silicone is especially employed in military industry in the beginning, after world war ii, as the silica gel has warm(60℃ to 230℃) special heat-resistant material can reach (60℃ -- 300℃),wear-resistant, resistant against ozone, acid and alkali resistance, kink, uv resistance, good flexibility, environmental protection, harmless non-toxic tasteless, like performance, application range is gradually expanding Silica gel may be popular in small household electrical appliances (coffee pot, kettle, iron, rice cooker, pan, disinfection cabinet, water dispensers, jam machine, oven, gas appliance, water heater) and several electronic products as supporting, auto parts, medical, etc at home and abroad has grown to be so common, together with the quickening of the operation of specialization, the petroleum chemical industry, medicine, food, biological, chemical, environmental protection, paint, textile, papermaking, printing ink, plastics along with other industrial fields are popular, silica gel products quality and level can also be on a new step. Silicone products compared to the plastic products, plastic products, whether it's service life and environmental protection are far in front of heat-resistant, silica gel products gradually replace plastic products, plastic products for daily necessities of life is only a matter of time.

Silica's application

1> in rubber applications: reinforcement of silicone rubber, fumed silica is the foremost. When adding fumed silica can improve the maximum strength after 40 times, can raise the yield point modulus of around 1O times, elongation, creep properties can be quite significant improvement. 2> sealants and adhesives from the application: used as a thickener and thixotropic agent, can boost the bond strength to be sure the free flow of preventing caking and sagging in the curing period, scattered fall, depression, to maintain transparency , Reinforcement, shear and so forth. 3> Application in plastics: plastic products can boost the density, finish and wear resistance. If, through appropriate surface modification, you can achieve the purpose of strengthening and toughening of plastic concurrently. Fumed silica will be included in the polyethylene, by special methods, can silica dispersed inside the matrix, a process of high wear. 4> thixotropic polyester gel coat resin application: increase the risk for product more uniform thickness, shrinkage, more in accordance with design requirements 5> From the putty application: a good anti-settling effect and ideal thixotropy. 6>in coatings applications: to deliver anti-caking, anti-sagging, emulsification, extinction, suspending, thickening and thixotropic as well as other functions.
