Background PPS
Polyphenylene Sulfide (PPS) is a heat resistant crystalline polymer with simple chemical construction as shown in Fig.1. This polymer has a high melting point of about 280°C, has outstanding chemical resistance and is non-burning by established industry flammability test without any flame retardant chemicals.
Chemical Structure
DIC-PPS which is filled with fiber reinforcement and/or mineral filler possesses an unique combination of properties of interest to the designer and processor. It combines the high performance usually associated with specialty plastics and the excellent processing characteristics of typical engineering plastics. It is thermally stable and exhibits excellent mechanical properties as well as dimensional stability.
Two types of PPS are available. One is the cross-linked molecular construction polymer based compounds; these are especially excellent rigidity and lower creep deformation under elevated temperature. The other is the linear molecular construction polymer based ; these have excellent toughness and lower water absorption than former, because of its high purity polymer.
This combination of superior properties and process ability provide the designer and processor with a unique material in applications.
Summary
DIC-PPS offers:
• Heat Resistance
• Superior Strength and Modulus
• Inherent Flame Resistance
• Excellent Dimensional Stability
• Chemical Resistance
• Excellent Electrical Properties
• Molding of Intricate and Precision Parts
