How to Increase Both Toughness and Strength in Plastic?

High Toughness & Strength Solutions

Quick Answer: Using the right grade and dosage of Siya Polymer's impact modifier solves the problem of strong-but-brittle plastic, achieving a good balance between impact strength and mechanical strength.

Why This Happens

This is a classic engineering trade-off — the more "strong" (rigid) you make a plastic, the more brittle it tends to become, and increasing toughness can sometimes slightly compromise tensile strength or stiffness. Getting this balance right without the correct additive and correct dosage is genuinely difficult, and over-dosing an impact modifier can actually hurt stiffness and heat-deflection performance. Siya Polymer & Speciality Chemicals helps formulators find the sweet spot between these competing requirements.
