How to Improve Heat Resistance and Dimensional Stability in Engineering Plastics?

Heat & Dimensional Stability Solutions for Nylon, POM, ABS & PC

Quick Answer: Siya Polymer's engineering plastic compounds and heat-stabiliser additive packages improve heat deflection temperature and dimensional stability in nylon, POM, ABS and PC parts, reducing warping, shrinkage and softening under load.

Why This Happens

Engineering plastic components used near engines, motors, electrical fittings or hot-water lines often face a very specific failure — the part warps, shrinks unevenly, or softens and loses its shape once it is exposed to sustained heat or a hot-and-cold duty cycle. This is a common complaint with nylon (PA6/PA66), POM, ABS and PC parts that are otherwise mechanically strong at room temperature but fail dimensional-stability checks or warp during assembly once real operating temperatures are applied. Poor heat resistance also shows up as gate-area sink marks, bowing of long/flat parts, and loosening of press-fit or snap-fit joints over time. Siya Polymer & Speciality Chemicals helps manufacturers solve this with the right engineering-grade compound and heat-stabilisation approach, rather than over-designing the part.
