What is PA66 GF35?

PA66 GF35 is a 35% glass fibre reinforced plastic PA 66. It is often used in industries such as aviation and mechanical engineering. Compared to TECAMID 66 GF30 black this glass filled nylon 66 has improved stiffness yet again and can withstand high loads.

What type of material is PA66?

Poly (hexamethylene adipamide), Polyamide 66, or Nylon 66 (PA66) is an engineering-grade thermoplastic. PA66 has higher strength but lower impact resistance than PA6.

What is PA66 GF33?

DuPont™ Zytel® Nylon Resin — Zytel® 70G33HS1L NC010 — PA66-GF33. Supplier’s Site. Zytel® 70G33HS1L NC010 is a 33% glass fiber reinforced, heat stabilized polyamide 66 resin for injection molding.

Does polyamide absorb water?

Polyamide absorbs moisture easily in comparison to most thermoplastics. Moisture can cause bubbles, silver streaks, and material aging on the product if the polyamide molds with it. Thus, sufficient pre-dehumidification and drying is required.

Is polyamide water resistant?

Polyamide is a plastic-based fabric that is fully waterproof, consequently, it is used for a wide variety of things from waterproof jackets to kitchen utensils and even medical implants.

Why is it called nylon 6 6?

Nylon 6 is made from one monomer which has 6 carbon atoms whilst Nylon 66 is made from 2 monomers with each one having 6 carbon atoms, hence the Nylon 66 name.

Why do polyamides absorb water?

Water absorption occurs because of the chemical structure of polyamide. Water passes through amorphous parts between the amide syntheses and enlarges the distance between molecules. Polyamide properties vary depending on moisture absorption as the material naturally absorbs water.

Why polyamides can absorb some amount of water?

(1) Water Absorption Nylon resins absorb water due to the hydrophilicity inherent to the amide bonds in the resins. The equilibrium water contents vary according to the kind of polyamides and to the environmental conditions. The equilibrium water contents of nylon 6 resins vary according to the use conditions.
