Dimethyl Silicone Oil 100cst CAS 63148-62-9 Medium Viscosity Mold Release Agent for Plastic Injection

Dimethyl Silicone Oil 100cst CAS 63148-62-9 is medium-viscosity polydimethylsiloxane (PDMS) fluid.
It can form a thin and uniform isolating film on the mold surface to effectively reduce adhesion between plastic raw materials and molds. It features stable high-temperature resistance, favorable demolding effect and moderate residual level on finished products. It serves as a reliable silicone mold release agent extensively used in plastic injection molding processes.

Product Detail Page(Suitable for Alibaba International & Official Website)

Product Overview

Dimethyl Silicone Oil 100cst CAS 63148-62-9 is medium-viscosity linear polydimethylsiloxane (PDMS).
With proper viscosity and surface activity, this silicone fluid can form a thin, continuous and uniform isolating film on metal mold surfaces. It effectively lowers the adhesive force between molten plastic and mold cavity. It maintains stable performance under injection molding high-temperature environment. It is easy to operate and leaves moderate residues. It is an economical silicone mold release agent specially suitable for plastic injection molding production.

Product Properties

Clear, colorless, transparent oily liquid, odorless
Kinematic viscosity: 100 mm²/s (25℃)
Good thermal stability under molding working temperature
Excellent film-forming ability to form uniform separation layer
Low surface tension, outstanding demolding property
Chemically inert to most engineering plastics and metal molds
Low volatility, stable performance during continuous production

Core Advantages

  1. Superior mold release effect, avoid plastic products sticking to molds
  2. Good high temperature resistance, suitable for conventional injection molding processes
  3. Uniform film formation, help obtain smooth surface of molded parts
  4. Moderate residual property, convenient for subsequent printing, spraying under correct usage
  5. Wide compatibility with PP, PE, ABS, PVC and other plastic materials
  6. Easy dilution and spraying, suitable for automated production lines

Main Applications

100cst Dimethyl Silicone Oil acts as medium viscosity mold release agent for plastic injection.
Typical applications: plastic injection molding release agent, blow molding separator, rubber molding auxiliary agent, casting release medium, plastic parts forming processing.

Usage Guidance

Can be directly coated or diluted with suitable solvent before spraying.
Control spraying dosage to prevent excessive silicone residue affecting post-process.
Keep working temperature within recommended range.
Carry out small trial production before mass manufacturing.
Avoid long-term mixing with strong alkaline substances.

Packing & Storage

Standard package: 25kg plastic drum; small test samples are available.
Keep container tightly sealed. Store in cool, dry and ventilated warehouse. Keep away from open flame, high temperature and strong oxidants. Prevent water and impurities from contaminating the product during transportation.
