Product Description

Silicone Polydimethylsiloxane Rubber CAS 63394-02-5 For Aircraft Components (PDMS)

Polydimethylsiloxane (PDMS) Silicone Rubber – Technical Overview

Description

Polydimethylsiloxane (PDMS) is a thermosetting silicone elastomer known for its flexibility, thermal stability, and biocompatibility. It exists in liquid (uncured) and rubber (cured) forms, widely used in medical devices, electronics, coatings, and industrial molds.

Specification

Parameter	Specification
CAS No.	63148-62-9 (varies by grade)
Chemical Formula	(C₂H₆OSi)ₙ
Appearance (Uncured)	Clear, viscous liquid
Appearance (Cured)	Translucent to opaque elastomer
Viscosity (Uncured, cP)	100–1,000,000 (adjustable)
Shore Hardness (Cured)	10A–80A
Tensile Strength	0.5–10 MPa
Elongation at Break	100–1200%
Thermal Stability	-50°C to +250°C (short-term 300°C)
Dielectric Strength	~20 kV/mm
Biocompatibility	ISO 10993/USP Class VI compliant (medical grade)

Key Features

✔ Extreme temperature resistance – Performs in freezing and high-heat environments.
✔ Chemically inert – Resistant to water, UV, and solvents (except hydrocarbons).
✔ Soft & elastic – Mimics human tissue (ideal for prosthetics/wearables).
✔ Non-toxic & odorless – Safe for medical/food contact (FDA-approved grades).
✔ Excellent electrical insulation – Used in potting/encapsulation.

Applications

1. Medical & Healthcare

Implants (catheters, tubing, breast implants).
Wound care (silicone adhesives).

2. Electronics

Encapsulation (protects circuits from moisture/dust).
Keypads/Touchscreens (flexible conductive coatings).

3. Industrial

Molding (for resins, candles, low-melt alloys).
Gaskets & Seals (high-temperature resistance).

4. Consumer Products

Kitware (baking molds, spatulas).
Cosmetics (silicone primers, hair conditioning agents).

Curing Methods

Heat Cure (HTV) – For high-strength applications.
Room-Temperature Vulcanization (RTV) – Two-part (A+B) or moisture-cured (RTV-1).
Platinum or Peroxide Catalysts – Determines curing speed/biocompatibility.

Packing & Storage

Uncured Liquid: 1 kg, 5 kg, or 20 kg pails/drums (airtight to prevent moisture cure).
Cured Sheets/Rods: Custom-cut sizes.
Storage: <30°C, away from direct sunlight (uncured lasts 6–12 months).

SILICONE RUBBER Usage And Synthesis

Chemical Properties

The mechanical properties of silicone elastomers at room temperature are inferior to those of other elastomers.Silicone elastomers are unaffected by oxygen and ozone on natural ageing. Because of their water-repellency, silicone elastomers are not seriously affected by aqueous solutions of most chemical reagents.They are attacked by strong acids and alkalis. General purpose elastomers are swollen by aliphatic, aromatic and chlorinated hydrocarbons but much improved resistance is shown by nitrile- and fluorine-containing silicones. In general, room temperature- cured materials have lower solvent resistance.

Uses

The major use of conventional silicone elastomers is in aircraft components where high and low temperature properties and electrical insulation characteristics are utilized, e.g. gaskets, sealing strips, ducting and cable insulation. Room-temperature vulcanizing silicone elastomers are used for the encapsulation of electronic and electrical equipment and for caulking. Liquid silicone elastomers are used for injection moulding of such components as seals, diaphragms and O-rings. They are ideal for moulding intricate shapes and are particularly suited to high-speed, high-volume operations.
