If you’re in the rubber business, you already know how important rubber sheet release agents are. They stop raw rubber sheets from sticking together, keep production steady, improve quality, and cut down on scrap and costs.
As a professional manufacturer and supplier, Shenyang Longgreen Science & Technology Co., Ltd. offers five high-performance release agents in powder, granular, liquid, paste, and block forms to fit different rubber production processes. Each type has its own strengths, whether you’re running internal mixers, extrusion lines, continuous processing, or just storing semi-finished rubber.
This simple guide will help you quickly pick the right one by explaining the main features and differences.
LongGreen 1210 Powder Rubber Sheet Release Agent
LongGreen 1210 is an off-white to light yellow powder. It stays well suspended in water and won’t settle quickly. It forms a soft, flexible separating layer and works well at controlling dust. When you mix it into rubber later, it blends in completely without hurting strength or aging resistance.
We recommend using it at around 3.0±1% concentration.
It works especially well for internal mixing, especially with high-viscosity rubber. In hot weather, you can use a slightly higher concentration to keep the anti-stick effect stable.
LongGreen 1230 Granular Rubber Sheet Release Agent
LongGreen 1230 is a white to light yellow granular product with no fillers and zero dust. That makes weighing and handling much cleaner and easier. It contains no silicone or phosphate, so it works well with almost all rubber compounds.
It dissolves easily in hot water at just 1.0–2.0%, so you use less material overall. This is your best choice if you run a clean, high-standard production line.
LongGreen 8091 Liquid Rubber Sheet Release Agent
LongGreen 8091 is a white to light yellow viscous liquid. It forms an extremely thin separating film, perfect for high-speed continuous processing. It’s dust-free, won’t pollute steam-curing water, and keeps your equipment and workshop clean.
It won’t damage the physical properties or aging performance of finished rubber parts. You can adjust the concentration from 3% to 22% based on your process. Just keep in mind: it’s not ideal for semi-finished products that need strong bonding later.
LongGreen 8092 Paste Rubber Sheet Release Agent
LongGreen 8092 is an off-white to light yellow paste that dries very fast and forms a smooth, elastic separating layer quickly. It won’t settle or form hard clumps, and it doesn’t stick to processing equipment, so you spend less time cleaning and maintaining machines.
You can even mix it with powder products to lower total cost while keeping performance steady. Dilute it with water at 1:10 to 1:20 before use. It fits internal mixing, extrusion, and continuous production lines.
LongGreen 8093 Block Rubber Sheet Release Agent
LongGreen 8093 is an off-white to light yellow block product with a very high dilution ratio — over 1:20, making it very cost-effective for large-scale use. It’s dust-free, won’t clump, and is safe to handle.
You can also use it with powder products for even better separation. When dissolving, make sure water temperature is above 65°C for full dispersion. It’s widely used for separating semi-finished products in the tire and rubber goods industry.
