The manufacturing of high-performance silicone rubber relies on precise control over material properties and processing parameters. At the forefront of achieving these exacting standards is Hydroxy Terminated Polydimethylsiloxane (PDMS), a key silicone fluid identified by CAS number 70131-67-8. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated supplier, offers this critical material that significantly enhances the capabilities of silicone rubber formulations.

PDMS with terminal hydroxyl groups, often referred to as silicone rubber structural control agent, plays an indispensable role during the compounding stage. When silicone rubber is mixed with reinforcing fillers like white carbon black, the interaction between the polymer chains and the filler particles is crucial for determining the final mechanical properties and processability of the rubber. Hydroxy Terminated PDMS is adept at mediating these interactions. It helps to prevent excessive aggregation of the filler particles and reduces the viscosity of the mixture, making it easier to mix, extrude, and mold.

This ability to control the structuring effect not only streamlines the manufacturing process but also contributes to improved storage stability of the uncured silicone rubber compound. This means that formulated rubber remains workable for longer periods, reducing the risk of premature curing or degradation. For manufacturers, this translates directly into reduced material waste, higher production yields, and consistent product quality, making it a prime example of an effective plastic auxiliary agent.

Beyond its role in controlling viscosity and preventing premature crosslinking, the presence of hydroxyl groups in PDMS allows it to participate in the curing process of certain silicone elastomers. This reactive nature can contribute to the overall crosslink density and network integrity of the final cured product, further enhancing its mechanical strength and durability. Manufacturers often seek out such specialized additives when developing advanced silicone formulations that require superior resilience and longevity.
