Compared with PVC, what are the advantages of epoxy resin board in EPS system?

Compared with PVC, epoxy resin boards have the following advantages in EPS systems:

Strong adhesion: The existence of inherent hydroxyl and ether bonds in the molecular chain of epoxy resin makes it have high adhesion to various substances. This strong adhesion makes it excellent in applications where high strength bonding is required.

Low shrinkage: Epoxy resins show very low shrinkage during curing (less than 2%), which makes them very popular in precision manufacturing and applications requiring dimensional stability.

Excellent mechanical properties: The cured epoxy resin system has excellent mechanical properties, including high strength and high rigidity. This makes it excellent in applications that require it to withstand mechanical stresses and shocks.

Excellent electrical properties: the cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance. Therefore, epoxy resin boards are widely used in electrical and electronic fields, such as circuit boards, transformers and so on.

Good chemical stability: Generally, the cured epoxy resin system has excellent alkali resistance, acid resistance and solvent resistance. This makes it widely used in the chemical industry and in environments where corrosion resistance is required.

Good dimensional stability: The combination of many of the above properties makes the epoxy resin system have outstanding dimensional stability and durability. This means that the epoxy sheet is able to maintain its shape and size during use and is not easily deformed.

Wide application fields: epoxy resin board is widely used in water conservancy and hydropower insulation parts, switch cabinet insulation parts, semiconductor insulation parts, electrified railway insulation parts, Marine manufacturing insulation parts, busbar trough insulation spacer gasket and frequency conversion insulation parts.

Wear resistance: The wear resistance of epoxy resin is higher than that of PVC, which is particularly important for the wear resistance requirements in EPS systems.

Stability to temperature changes: there is basically no change in epoxy resin, and PVC thermal expansion and contraction is relatively large, which makes epoxy resin maintain better stability under temperature changes.

Chemical corrosion resistance: epoxy resin is resistant to a certain degree of chemical corrosion, and chemical resistance (acid, alkali, methanol) is better than PVC.

CONCLUSION

In summary, compared with PVC in EPS system, epoxy resin plate provides stronger adhesion, lower shrinkage, better mechanical and electrical properties, better chemical stability and dimensional stability, as well as a wider range of applications, especially in wear resistance, temperature stability and chemical corrosion resistance show obvious advantages.
