Discover Butyl Rubber Sheets (IIR): Properties and Applications

### Discover Butyl Rubber Sheets (IIR): Properties and Applications
 
**Introduction:**
Butyl Rubber Sheets, known in the industry as IIR  Rubber, are an essential component in various industries due to their unique properties. This article explores the world of IIR rubber sheets, delving into their characteristics, benefits, and diverse applications.
 
**What is IIR Rubber?**
IIR, also known as Butyl Rubber, is a copolymer composed of isoprene (in small quantities sufficient for sulfur cross-linking) and isobutylene. Typically, IIR has a density of approximately 0.92 g/cm³. The rubber grades vary based on the double bond content relating directly to the proportions of isoprene and isobutylene, and are also graded based on the rubber's viscosity.
 
**Key Properties of IIR/Butyl Rubber Sheets:**
1. **Exceptional Gas Permeability Resistance:** Due to the dense molecular structure of IIR rubber, these sheets exhibit significantly low gas permeability compared to other types of rubber sheets available in the market.
2. **Abrasion Resistance:** IIR sheets show high resistance to abrasion and wear.
3. **Good Rebound Resilience Properties:** At room temperature, IIR rubber sheets have low rebound rates, which increase with rising temperatures.
4. **Oil and Chemical Resistance:** These sheets are resistant to vegetable and animal oils, synthetic hydraulic oils, alcohols, acids, alkalis, salts, and polar solvents.
5. **Environmental Resistance:** The predominantly saturated structure of IIR rubber lends it excellent resistance to degradation from oxygen, ozone, steam, heat, and UV rays.
6. **Operating Temperature Range:** IIR rubber sheets can be used in temperatures ranging from -50 to +150°C, similar to EPDM rubber sheets.
 
**Applications of IIR/Butyl Rubber Sheets:**
1. **Automotive Industry:** Used as inner liners due to their air retention properties and low gas permeability.
2. **Roofing Materials:** Serve as a waterproofing element in roofing, providing resilience against harsh weather conditions.
3. **Chemical Tank Linings:** Used to line chemical tanks due to their chemical and corrosion resistance.
4. **Vibration Damping:** Efficient in absorbing mechanical energy and reducing vibrations.
