PA Tougheners

Product Overview：

This product series is based on polyolefin elastomer (POE) as the matrix resin, with maleic anhydride (MAH) active groups introduced via melt grafting. It is a high-performance nylon toughening modifier that can be used both as a compatibilizer and as a toughening agent. It is particularly suitable for room-temperature and low-temperature toughening, reinforced toughening, and super-toughening of polyamides (PA6, PA66).

Core Value：

By adding this toughener series, ordinary PA6 can achieve – or even surpass – the low-temperature toughness and impact resistance of PA12, significantly reducing material costs and providing a cost-effective solution for low-temperature applications.

Mechanism of Action：

The polymer backbone is a flexible polyolefin elastomer, onto which maleic anhydride (MAH) reactive groups are grafted.

Elastomer part：provides super toughness through micro-crosslinking and microcrystalline domains, imparting excellent impact resistance.

Maleic anhydride groups： react readily with amine end groups of nylon via steric hindrance, hydrogen bonding, and chemical coupling, forming strong linkages with the nylon matrix.

Synergy：the elastomer toughens while the anhydride groups enhance compatibility, enabling the co-blend system to combine properties of different materials, bridging polar and non-polar components.

In glass-fiber reinforced nylon applications, the toughener also reacts with hydroxyl groups on the fiber surface, improving interfacial adhesion and simultaneously boosting both tensile strength and impact strength.

Performance Advantages：

Excellent ultra-low temperature toughening:

· Maintains outstanding impact toughness at -40°C.

· PA6 + 18% MX03 achieves notched impact strength of 23.7 kJ/m² at -40°C, with a retention rate of approx. 30% of room-temperature performance.

· Effectively resolves the industry pain points of low impact strength and brittleness of nylon under dry and low-temperature conditions.

Replace PA12 with PA6 for major cost reduction:

·With this toughener series, standard PA6 can match the low-temperature toughness and impact resistance of PA12.

· PA6 raw material costs are far lower than PA12, yielding significant overall cost savings.

· Suitable for applications that previously mandated PA12, such as pneumatic tubing and automotive components, where low-temperature performance is critical.

Multi-functional integration:

· Combines toughening + compatibilizing in one product.

·Works in PA/PE, PA/PP, and other alloy systems to improve alloy toughness.

· Compatible with glass fiber, mineral fillers, and other reinforcements for simultaneous reinforcement and toughening.
