Hydride terminated Polydimethylsiloxane

1. Hydride Terminated Polydimethylsiloxane is usually used as a silicone end-capping agent.

2. Due to Hydride Terminated Polydimethylsiloxane containing reactive Si-H groups in the molecular structure, it can be used in the synthesis of copolymer macromolecules by hydrosilylation. The synthesis of copolymer macromolecules can be made into a series of reactive silicone oils.

3. Hydride Terminated Polydimethylsiloxane is usually used to produce textile softeners, block silicone oil, and surface-active agents.

4. As a chain extender for addition-type liquid silicone rubber, adding a crosslinking agent for forming a hot vulcanized silicone rubber can improve the product's elongation at break, increase toughness, and reduce hardness;

5. As a waterproofing agent and softener for natural and synthetic fabrics;

6. As the special silicone surfactant;

7. Hydride Terminated Polydimethylsiloxane is the basic intermediate raw material that can be used in the manufacture of a variety of end-group reactive linear modified silicone oil.

8. As the key intermediates of block copolymerization reaction.

9. It is the starting material of organic polymer-modified materials, which can be a modification of the reaction, such as plastic resin.

Hydride Terminated Polydimethylsiloxane for silicone rubber

Hydride Terminated Polydimethylsiloxane also referred to as di-Me crosslinker, this silicone fluid is the key raw material ingredient to initiate the curing process of a two-component silicones elastomer/rubber formulation. These formulated specialty elastomers include silicone foam, liquid silicone rubber (LSR), heat-cured rubber (HCR), and room-temperature cure (RTV) silicone rubbers.

These silicone elastomers are then used in a diverse range of high tech specialty markets such as Healthcare, Automotive, Aerospace, Solar, Textiles. In the healthcare market, silicone elastomers are used as valves in medical devices and equipment and in long-term implant applications like pacemakers and heart valves. In the automotive market, the formulated silicone elastomers are used to dissipate heat in high-temperature environments such as in electric vehicles. In the energy market, the formulated silicones dissipate heat in energy storage units to support an uninterrupted power supply.

Due to the Si-H functionality, these products are able to react in a catalyzed hydrosilation reaction with compounds bearing carbon-carbon double bonds in 1-position, e. g. vinyl siloxanes, alpha-olefins, or other unsaturated compounds.

Common hydrosilation reaction catalysts are group VIII metal compounds, especially platinum compounds. In compounding addition curing silicone elastomers chain extenders reduce the crosslink density and thus the hardness of the resulting elastomer. The use of chain extenders allows compounding elastomers with relatively low shore hardness using low viscosity and easy to process vinyl silicone polymers in the formulation.
