FAQ

How do I prevent additive blooming and migration in finished parts?
Select additives with appropriate molecular weight and polymer compatibility. Higher MW additives migrate less. Consider encapsulated or polymer-bound versions for critical applications. Proper dosage levels also prevent oversaturation that leads to blooming.
What's the difference between primary and secondary antioxidants?
Primary antioxidants like Irganox 1010 scavenge free radicals to prevent oxidation initiation. Secondary antioxidants decompose hydroperoxides that form during oxidation. Use both together for synergistic protection - typical ratio is 3:1 primary to secondary.
Can I substitute calcium carbonate with talc as a filler?
Both are mineral fillers but have different effects. Calcium carbonate is more cost-effective and provides better impact properties. Talc offers superior stiffness and heat deflection temperature. Choose based on your primary performance requirement and cost targets.
How do I ensure flame retardant compliance with UL standards?
Work with UL-recognized component suppliers and follow their recommended formulations. Maintain consistent additive loadings and processing conditions. Third-party testing is required for UL listing - budget for initial qualification and annual audits.
What are the best alternatives to phthalate plasticizers?
DOTP, DINCH, and citrate esters offer similar performance with better regulatory profiles. DOTP provides closest performance match to DINP. Citrates work well for food contact. Expect 10-30% price premium but improved market acceptance.
