Bio‑Based Release Wax Rice Bran Wax Derivative CAS 8016‑60‑2 is refined and chemically modified plant‑based wax derived from rice‑bran oil by‑product. As a renewable bio‑based alternative to fossil‑sourced synthetic wax, this product meets food‑contact requirements and exhibits partial biodegradability. It provides coordinated internal and external lubricating as well as mold‑release functions for bioplastic and thermoplastic polyurethane (TPU). During melt processing, it reduces polymer melt vi

Product Detail

Product Detail Page: This rice‑bran‑wax derivative is manufactured by extracting crude natural rice bran wax from rice‑bran oil, followed by purification, controlled chemical modification, filtration, cooling, flaking or fine pulverization. Each production batch is tested for melting point, saponification value, acid value, thermal stability, food‑contact relevant migration index, biodegradability performance, lubricating and mold‑release properties to guarantee consistent quality for sustainable polymer compounding.

Modern bioplastic and TPU manufacturing faces distinctive formulation challenges. Conventional fossil‑based petroleum or lignite‑sourced wax additives cannot satisfy sustainability and circular‑economy requirements. Many common natural unmodified plant waxes show insufficient thermal resistance under TPU and bioplastic processing temperatures, leading to premature decomposition, smoke generation and surface defects on molded components. In bioplastic compounding, inadequate internal lubrication increases melt viscosity and raises extruder torque. Without proper external releasing performance, hot bioplastic or TPU melt tends to adhere firmly to mold cavities. Sticking causes tearing, deformation and surface blemishes on finished molded goods. Continuous production also suffers from progressive plate‑out deposits, which force frequent mold cleaning and reduce overall production efficiency. Meanwhile, for articles intended for food‑contact applications, strict restrictions exist on additive migration.

When homogeneously blended with bioplastic or TPU base resin, pigments and fillers at recommended dosage, the bio‑based rice bran wax derivative melts gradually under processing heat and mechanical shear. The internal‑lubricating fraction reduces intermolecular friction within molten polymer, lowering shear resistance and stabilizing extrusion torque during twin‑screw compounding. A portion of modified wax migrates towards the metal‑melt contact boundary and builds a continuous thin low‑friction isolating film. This slippery interfacial layer reduces resin‑metal adhesion, facilitates smooth demolding of intricate bioplastic and TPU molded parts, and suppresses plate‑out accumulation on die lips and mold surfaces. Benefiting from its plant‑derived molecular structure, this wax offers partial biodegradability and satisfies food‑contact migration specifications, making it suitable for eco‑friendly articles that require direct or indirect food contact.

Precise dosage control is essential for sustainable formulation design. Under‑dosage results in insufficient lubrication and mold‑release performance, high processing torque, sticking defects and rapid mold fouling. Excessive loading may impair mechanical properties such as tensile strength and abrasion‑resistance of finished TPU and bioplastic products, and may induce surface blooming. Laboratory compounding and injection‑molding trials are strongly recommended before formal mass‑scale production. This bio‑based release wax can be used synergistically with antioxidants, anti‑hydrolysis stabilizers, mineral fillers for PLA, PBAT and various TPU grades.

For compounding operations, flaked or powdered rice‑bran‑wax derivative is added during high‑speed premixing with base resin, stabilizers and fillers prior to twin‑screw extrusion pelletizing or direct injection molding.

Keep the product sealed against moisture and foreign particulate contamination. Long‑term storage under elevated ambient temperature may trigger mild softening and caking of wax flakes and powder.

Major application fields: sustainable bio‑based mold‑release and lubricating processing aid for PLA, PBAT and other biodegradable bioplastics; food‑contact‑grade lubricant‑release additive for soft and hard TPU injection‑molded articles; eco‑friendly wax auxiliary for modified sustainable polymer compounding.

Store the product in tightly‑sealed original bags within 15‑30℃, maintain dry storage and avoid direct sunlight.
