Product Overview

Yinuo New Material Technology (Heze) Co., Ltd. offers a high-performance release agent specifically formulated for polyurethane (PU) elastomer applications. Developed with advanced modified silicone technology, our release agent delivers superior release performance, excellent surface finish, and reliable mold protection for cast polyurethane products.

Designed to meet the demanding requirements of PU elastomer processing, our release agent effectively prevents adhesion between the polyurethane elastomer and the mold surface, ensures smooth and convenient demolding, and significantly extends mold service life.

Key Features & Benefits

Superior Release Performance
Our advanced modified silicone formulation provides exceptional smoothness and isolation properties, ensuring quick and clean release of PU elastomer parts from the mold. It effectively prevents sticking and tearing, minimizing casting defects such as surface imperfections, drag marks, and uneven finishes.

Excellent Surface Finish
Castings produced with our release agent feature bright, glossy, and defect-free surfaces with precise duplication of mold details. The superior finish quality enhances the aesthetic appearance of finished parts and reduces the need for secondary surface treatment.

Broad Temperature Range Stability
Our release agent remains effective over a wide temperature range, maintaining stable performance under both ambient and elevated processing conditions. It exhibits excellent high and low temperature resistance, ensuring consistent results throughout prolonged production cycles.

High Dilution Ratio – Cost Effective
As a concentrated formulation, our release agent offers excellent dilution ratios – typically 20 to 40 times with suitable solvents – significantly reducing consumption costs while maintaining superior performance. Its high efficiency allows for minimal application quantities per cycle, further lowering overall production expenses.

Non-Corrosive & Mold Protection
Our release agent does not corrode molds or leave harmful residues on the mold surface. It effectively reduces mold fouling and buildup, minimizes mold maintenance requirements, and extends tool life.

Post-Processing Compatibility
Parts produced with our release agent feature clean surfaces that do not interfere with subsequent painting, bonding, coating, or printing operations. This ensures seamless integration into your existing production workflow.

Low Odor & Operator Safe
Our release agent features low odor formulation- with minimal solvent emissions, creating a safer and more comfortable working environment for your operators.

Applications

Our PU elastomer release agent is widely used in the production of polyurethane elastomer components across various industries, including:

• PU rollers, wheels, and bushings

• Industrial PU parts and mechanical components

• Cast polyurethane elastomer products

• PU microcellular elastomers and integral skin foam systems

• PU RIM (Reaction Injection Molding) processing

• Polyurethane shoe soles and footwear components

• Automotive polyurethane parts

It is suitable for both casting and injection molding processes, and compatible with a wide range of polyurethane systems including polyester-based and polyether-based formulations.

Usage Instructions

• Thoroughly clean the mold surface to remove all traces of previous coatings and oils before first use

• Dilute the concentrated release agent with the recommended solvent (such as dichloromethane, toluene, xylene, gasoline, or 120# solvent oil) at the appropriate ratio – typically 20 to 40 times, depending on part complexity and processing conditions

• Apply uniformly to the mold surface using spray or brush application methods

• Allow the solvent to volatilize completely before proceeding with the molding cycle

• Reapply a light coating before each molding cycle for optimal results

• A small test application is recommended to determine the optimal dilution ratio and suitability for specific production conditions
