*PBT resins combine high mechanical, thermal and electrical properties with very good chemical resistance and very good dimensional stability. Characterized by their very good resistance to a variety of chemicals, including aliphatic hydrocarbons, petrol, oils and greases, dilute acids and bases, detergents and most aqueous salt solutions at ambient temperatures. High dielectric strength is a special attribute of PBT resins – even in high temperatures and over widely varied environmental conditions. They also offer low moisture absorption, low warp, high heat resistance and inherent lubricity.
