SEMI DULL PA6 RESIN FOR TEXTILE GRADE

    Nylon 66 has chemical and physical properties very similar to PA66, but has a lower melting point and a wider processing temperature range. It has better impact and dissolution resistance than nylon 66, but is also more hygroscopic. Since many quality properties of plastic parts are affected by hygroscopicity, this should be taken into account when designing products that use PA6. In order to improve the mechanical properties of Nylon 66 Material, various modifiers are often added. Glass fiber is the most common additive, and synthetic rubbers such as EPDM and SBR are sometimes added to improve impact resistance. For additive-free products, PNylon Pa6 shrinks between 1% and 1.5%. Adding glass fiber additives reduces shrinkage to 0.3% (but slightly higher perpendicular to the process). Shrinkage of molded components is primarily affected by the crystallinity and hygroscopicity of the material. Actual shrinkage is also a function of part design, wall thickness and other p…
