Polyamides (PA) are workhorse materials in many industries, valued for their strength and heat resistance. However, a common limitation of PAs is their susceptibility to impact failure at low temperatures, a critical concern for components used in cold climates or high-altitude applications. Addressing this challenge requires specialized polymer additives, and anhydride-modified polyolefin elastomers (POE-g-MAH) with a low glass transition temperature (Tg) have emerged as a highly effective solution. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing these advanced impact modifiers.

The glass transition temperature (Tg) of a polymer is a critical parameter that dictates its behavior at different temperatures. Below its Tg, an elastomer typically transitions from a rubbery, flexible state to a glassy, brittle state. By incorporating a POE-g-MAH modifier with a significantly low Tg into PA formulations, the overall Tg of the composite material is effectively lowered. This ensures that the modified PA remains flexible and capable of absorbing impact energy even when subjected to frigid temperatures. This characteristic is vital for applications where material integrity under stress at low temperatures is non-negotiable.

The mechanism behind this improvement involves the grafted maleic anhydride groups on the POE-g-MAH reacting with the PA matrix, creating a strong interface. The elastomer's inherent flexibility, maintained even at low temperatures due to its low Tg, dissipates impact energy effectively, preventing crack propagation. This makes POE-g-MAH an ideal choice for enhancing the low-temperature impact performance of PA, which is often sought after in the automotive industry for exterior components, and in electronics for housings exposed to varying environmental conditions.
