Acrylonitrile Butadiene Styrene (ABS)

Keep pellets sealed, clean and dry. Because absorbed moisture can generate splay, bubbles and surface defects during moulding, use the supplier’s drying recommendation and avoid prolonged overheating. Provide ventilation around processing equipment because thermal degradation can release styrene, acrylonitrile-related and other decomposition vapours.
HSE control principle
Use the current product-specific SDS, local dangerous-goods requirements, receiving-site risk assessment and applicable engineering standards. Website text should never substitute for a supplier SDS or site procedure.

A technically meaningful RFQ should define the key quality parameters that control ABS processing and finished-product performance. Typical requirements include MFR/MVR, density, impact strength, tensile modulus/yield, Vicat/HDT, moisture, colour/gloss, and flammability. MFR/MVR should be tested according to ISO 1133 or ASTM D1238 to verify process flow, while density under ISO 1183 or ASTM D792 supports product identity and lot consistency. Impact strength, measured by ISO 179/180 or ASTM D256, is a key toughness parameter, and tensile modulus/yield under ISO 527 or ASTM D638 confirms rigidity and strength. Thermal performance should be assessed through Vicat and HDT according to ISO 306 and ISO 75. Moisture may be checked by supplier methods or Karl Fischer where appropriate because it affects processing stability. Colour and gloss should be evaluated instrumentally for appearance-sensitive applications, while UL 94 flammability testing should be specified where required for electrical or electronic applications. Final test methods should match the producer specification, customer standard, and intended application.
