Petroleum Resin
Definition:
Petroleum resin, also known as hydrocarbon resin, is a thermoplastic polymer derived from petroleum-based feedstocks.
Properties:
1. Chemical resistance
2. Water resistance
3. Thermal stability
4. Adhesion
5. Flexibility
Types:
1. Aliphatic resins (e.g., polyalphaolefins)
2. Aromatic resins (e.g., coumarone-indene resins)
3. Hydrogenated resins (e.g., hydrogenated styrene-butadiene)
Applications:
1. Adhesives (hot melt, pressure-sensitive)
2. Coatings (paints, varnishes)
3. Construction (sealants, caulks)
4. Printing inks
5. Rubber compounding
6. Packaging (hot melt coatings)
7. Automotive (sealants, adhesives)
Benefits:
1. Excellent chemical resistance
2. Good thermal stability
3. Flexibility and toughness
4. Low viscosity
5. Cost-effective
Specifications:
1. Softening point: 80-150°C
2. Molecular weight: 500-5000 g/mol
3. Density: 0.9-1.1 g/cm³
4. Viscosity: 100-1000 mPa·s
