Whether you’re working on a new application or considering a material switch, selecting the right material can expand your success. Did you know that with the right formulation, you can achieve properties that are as good or better than that of PA 6,6 using materials such as PA 6, PK, PBT/PET, PP, polymer blends and even post-industrial recycled blends? Processing conditions can cause material properties to shift from the values stated in the information.

These materials are semi-crystalline and deliver excellent chemical resistance, low moisture uptake, and dimensional stability similar to nylon (PA6 and PA66). KEY CHARACTERISTICS • Chemical resistance • Maintaining high impact performance at low temperatures • Low moisture uptake • Dimensional stability comparable to nylon • Higher impact resistance than short fiber alternatives • Eco-conscious alternative to nylons • More cost-effective solution than specialty nylons • Available in non-PFAS* formulations to achieve UL 94 V-0 flame rating at 1.5 mm MARKETS & APPLICATIONS These materials are for use in applications traditionally made of metal requiring moisture, chemical and cold impact performance requirements, including: • Industrial – pipes, tubing, fluid management • Electrical & Electronics – connectors, battery components, battery housings • Transportation – under-the-hood fuel/ chemical contact components, non-structural interior components • Oil & Gas – fuel pump components, fuel doors PRODUCT BULLETIN * Non-PFAS flame-retardant (FR) grades are manufactured without intentionally added PFAS-based raw materials.

Sourcing materials from overseas made the company vulnerable to quality inconsistencies and long lead times. Instead of purchasing pre-fabricated acrylic sheet that contained a costly diffusion additive, the Smartbatch solution enabled the customer to reduce its material costs by 50%. This saved the customer over $25,000 in annual material costs in addition to resolving its toughest design challenges.
