Typical Applications of PPTD20 in Automotive Interiors
With the continuous growth of automotive lightweight and cost control demands, PPTD20 has become one of the most widely used thermoplastic materials in the automotive interior field.
Typical Application Case: Instrument Panel Frame
The instrument panel is one of the most complex components. PPTD20 is extensively used for structural parts and internal frameworks.
Application Case: Door Panel Inner Liner
Door inner panel assembly usually contains multiple injection-molded parts, among which PPTD20 is extensively adopted.
Application Case: Pillar Trim
Pillar trim is the most mature sub-field for PPTD20 use in automotive interiors.
Key Points for Material Selection
Advantages: Good rigidity-toughness balance; Low shrinkage; Low VOC; Excellent grain replication; Cost advantage.
Disadvantages: Limited heat resistance; Lower surface hardness; Welding strength not as good as reinforced PA.
