Lubrizol 58212 NAT 021/022 IM TPU Elastomer – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Lubrizol 58212 NAT 021/022 in TPU formulations?

A: Lubrizol 58212 NAT 021/022 is a specialized internal mold release additive designed to improve demolding efficiency and surface finish in thermoplastic polyurethane (TPU) injection molding applications. It reduces adhesion between molten TPU and mold surfaces without compromising mechanical integrity or clarity.

Q2: Is this product compatible with all common TPU chemistries (e.g., polyester- and polyether-based)?

A: Yes, Lubrizol 58212 NAT 021/022 has been formulated for broad compatibility across standard aromatic and aliphatic TPU grades, including both polyester- and polyether-based systems. Compatibility should be verified under actual processing conditions due to formulation-specific variables.

Q3: How does this additive affect the physical properties of the final TPU part?

A: When used at recommended levels, Lubrizol 58212 NAT 021/022 typically has minimal impact on tensile strength, elongation, or hardness. Slight reductions in surface friction and improved gloss may be observed, but significant changes to key mechanical or thermal performance are not expected.

Q4: What is the typical dosage range for optimal performance in injection molding?

A: Dosage is formulation- and process-dependent, but Lubrizol 58212 NAT 021/022 is generally effective at low concentrations—typically ranging from 0.1% to 2% by weight relative to the base TPU resin. Optimization trials are recommended to balance release performance with end-use requirements.

Q5: Can this additive be used in transparent or color-critical TPU applications?

A: Yes, Lubrizol 58212 NAT 021/022 is designed to maintain optical clarity and color stability in TPU systems. It exhibits low volatility and minimal bloom tendency, supporting consistent appearance in high-gloss or transparent molded parts.
