Nylon 66 Resin

What is Nylon 66 Resin?

NY66 and NY6 (Nylon 6,6 and Nylon 6) are semi-crystalline engineering thermoplastics that can be easily colored, and that can be easily processed in both injection molding, and extrusion applications. Nylons are known to have excellent chemical resistance. Nylon 66 and Nylon 6 are two of the most commonly used engineering thermoplastics. In addition to chemical resistance, they also offer excellent abrasion resistance, and high resistance to fungal attacks. Both Nylon 66 and Nylon 6 are rigid materials with high heat resistance.

Physical properties of these materials can be enhanced through the use of additives. Addition of glass fibers and/or mineral fillers can increase flexural modulus values. Surface lubricity can be increased by addition of molybdenum disulfide, and heat stabilizers can be added to improve long term thermal stability. Impact modifiers can be added in order to obtain tough Nylon compositions.

Nylon products are affected by humidity because Nylons tend to absorb water, due to their hygroscopic properties. Absorbed water “plasticizes” Nylon. The absorbed water will reduce stiffness and will increase ductility. Absorbed water will also increase dimensions of parts molded from Nylons. While absorption of water is reversible, it must be taken into account when designing parts to be molded from Nylons.

Nylon is a very versatile material that is easily colored, and that is easy processed in both injection molding and extrusion applications.

Additives, Modifiers, and Reinforcing Agents:
  • Additives – UV stability, easy release (mold releases), colorants, and other stability additives
  • Modifiers – Flame retardants, impact modifiers, flow enhancers
  • Reinforcing Agents – Glass fibers, mineral fillers
