Precision Heat Stabilized Nylon Plastic Pellets PA6/PA66 For High Accuracy Optical Component Connectors

Product Description

The Heat Stabilized Nylon PA6/PA66 Compounds are engineered for optical component connectors where dimensional accuracy, thermal stability, and long-term reliability are critical. Unlike standard nylon, this grade incorporates special heat stabilizers and optimized polymer structures to reduce warpage, control shrinkage, and maintain mechanical integrity under fluctuating thermal environments.

In precision optical applications, even a micron-level deviation can lead to signal loss or misalignment. This material addresses such challenges by offering low warpage, high dimensional stability, and excellent resistance to environmental factors such as heat and moisture. It is widely applied in fiber optic connectors, optical device housings, and precision alignment structures.

Properties Data Sheet

Notes: The general guidelines are only for reference. Exact settings have to follow the product and machine conditions.

Avoid contact with other materials, dust and debris in the injection processing.

Avoid long time stay in the barrel in the injection processing.

Usage Notes

• Drying is essential: Dry at 90–100°C for 4–6 hours to avoid hydrolysis and surface defects.

• Molding recommendations: Injection temperature 260–290°C, mold temperature 80–100°C for precision part stability.

• Design notes: Optimize gate placement to minimize weld lines and shrinkage that could affect optical alignment.

• Storage: Keep sealed in moisture-proof packaging; process soon after drying.

• Color: Available in natural, black, and customized colors; natural color is suitable for transparent or semi-transparent optical parts.

Features, Advantages & Technical Highlights

• Excellent Dimensional Stability – Low shrinkage ensures tight tolerances required for optical connectors.

• Superior Heat Resistance – Maintains performance at 120–140°C continuous use without deformation.

• Low Moisture Absorption – Minimizes swelling that can alter optical alignment.

• High Mechanical Strength – Reinforced grades available for enhanced structural integrity.

• Surface Quality – Produces smooth surfaces, essential for precision connector mating.

• Electrical Insulation – Prevents signal interference, suitable for data transmission systems.

• Lightweight Design – Replaces metals, reducing weight without compromising durability.

Working Principle: By integrating heat stabilizers and tailored polymer chains, the nylon compound resists thermal aging and moisture-induced expansion. This ensures the optical connector maintains precise geometry, securing stable light transmission and minimizing signal loss.
