Characteristics

Good heat resistance and mechanical strength.

Excellent chemical resistance; good scratch resistance; poor hydrolysis resistance

Softening breakdown temperature is higher than UEW/130; easy to dye; low dielectric loss at high frequency; no salt water pinhole

Softening breakdown temperature is higher than UEW/130; easy to dye; low dielectric loss at high frequency; no salt water pinhole

Softening breakdown temperature is higher than UEW/155; straight soldering temperature is 390 °C; easy to dye; low dielectric loss at high frequency; no salt water pinhole

High heat resistance; excellent chemical resistance, high heat shock, high softening breakdown

High heat resistance; thermal stability; cold-resistant refrigerant; high softening breakdown; high thermal shock

High heat resistance; thermal stability; cold-resistant refrigerant; high softening breakdown; high heat rush
