Methyl phenyl rubber IOTA 3301 is a large molecule built on methyl phenyl silicone oil, carrying a large number of phenyl groups on its molecular chain. Beyond the heat resistance and dielectric properties common to methyl silicone gum, it offers better radiation resistance, ablation resistance, physical and mechanical properties, and excellent high and low temperature performance.

One gum, three functions — the phenyl content decides:

• Low phenyl content: the gum keeps a certain degree of flexibility at -110°C, and products made from it as base raw material perform well in ultra-low temperature working environments.

• Medium phenyl content: significantly improves the damping performance of the silicone rubber.

• High phenyl content: significantly demonstrates the radiation resistance of the silicone rubber.

Advantages at a glance

• Long-term storage stability

• Good damping performance (medium/high phenyl)

• High consistency, low volatility, odorless, excellent thermal stability

• Small compression deformation and resistance to saturated vapor pressure

• Insoluble in water, soluble in toluene and similar solvents

Applications

• Aviation, electronics, machinery and chemical industries: high and low temperature resistant sealing materials, waterproof and moisture-proof insulation materials.

• Medicine and hygiene: thanks to physiological inertness, usable for blood refrigeration sealing and medical tubing.

• Special sealing materials and molded products requiring radiation resistance, high temperature resistance and erosion resistance.

Packaging and storage: 25 kg plastic drums or 200 kg iron drums; load into clean, dry containers and store in a ventilated, dry warehouse. Transported as non-dangerous goods. Shelf life: 24 months.

FAQ

• Q: How do I choose the phenyl level for my compound? A: Define the primary function first — lowest temperature flexibility (-110°C class), damping, or radiation resistance — then select the matching phenyl content grade of IOTA 3301.

• Q: Is IOTA 3301 compatible with standard HTV processing? A: It is designed as a base raw gum for molded and sealing products; processing confirmation for your specific line is available on request.

• Q: What is the shelf life? A: 24 months under the recommended storage conditions.
