Q1: What is the primary function of Deuteron SO 300 Oil Elastomer in polymer formulations?
A: Deuteron SO 300 Oil Elastomer functions as a reactive processing aid and elastomeric modifier, enhancing melt elasticity, improving extrudate swell control, and contributing to better dimensional stability in thermoplastic elastomer (TPE) and compounded polyolefin systems.
Q2: Is Deuteron SO 300 Oil Elastomer compatible with common thermoplastic matrices such as PP, PE, and TPOs?
A: Yes — it demonstrates good compatibility with polypropylene (PP), polyethylene (PE), and thermoplastic polyolefin (TPO) blends. Its oil-extended structure promotes homogeneous dispersion and interfacial adhesion during compounding, especially in dynamically vulcanized systems.
Q3: How does Deuteron SO 300 Oil Elastomer differ from conventional plasticizers or non-reactive oil extenders?
A: Unlike non-reactive plasticizers, Deuteron SO 300 Oil Elastomer contains functional groups that support mild covalent interaction with polymer chains during processing, reducing volatility and migration risk while maintaining long-term elastomeric performance in finished parts.
Q4: What are typical dosage ranges when using Deuteron SO 300 Oil Elastomer in TPE formulations?
A: Dosage is formulation-dependent, but it is typically used at low concentrations to achieve desired elasticity and processability — generally ranging from 0.1% to 2% by weight relative to the base polymer, with optimization guided by rheological and mechanical testing.
Q5: Can Deuteron SO 300 Oil Elastomer be used in applications requiring FDA compliance for indirect food contact?
A: While Deuteron SO 300 Oil Elastomer is formulated with components commonly accepted in food-contact polymers, formal regulatory clearance depends on final formulation, processing conditions, and end-use requirements. Customers should conduct full regulatory due diligence and consult applicable regional guidelines before claiming compliance.
