Product type
Isophthalic polyester resin is a type of thermosetting polymer that is known for its excellent mechanical properties and chemical resistance. It is produced by the polymerization of isophthalic acid with glycols, resulting in a durable material that can withstand high temperatures and harsh environments. This resin is commonly used in applications requiring high strength and thermal stability, such as in the manufacturing of composites, coatings, and adhesives.
| Chemical resistance | Good resistance to acids and alkalis |
| Heat deflection temperature | Typically ranges from 70°C to 120°C |
| Viscosity | Varies from 200 to 8000 cP at 25°C |
| Curing agents | Typically requires hardeners like MEKP or BPO |
| Color | Usually clear to amber |
When selecting isophthalic polyester resin, consider the specific application requirements such as mechanical strength, thermal properties, and chemical exposure. It's important to specify the desired heat deflection temperature, viscosity, and any necessary curing agents. Additionally, inquire about certifications or compliance with industry standards if applicable, and determine the required quantities for your project to ensure optimal pricing.
