Shenyang LongGreen Science & Technology Co., Ltd. is pleased to introduce LongGreen 12X, a high-quality multifunctional rubber processing additive made for modern natural rubber mixing. As professional processing aids for natural rubber, this product makes the whole rubber production process—from mixing and shaping to vulcanization—easier and more efficient. It solves common problems that factories often face, helping manufacturers work faster, save money, and make sure their finished products are always good quality.
In natural rubber manufacturing, processing aids for natural rubber are a must-have. Natural rubber is great for elasticity and strength, but it’s thick and hard to work with. This causes a lot of trouble: fillers like carbon black don’t mix evenly, mixing takes too long, it uses too much energy, rubber sticks to equipment, extrusion and calendering don’t go smoothly, molds fill slowly, it’s hard to take products out of molds, and sizes aren’t consistent. All these problems mean less output, more defective products, and higher costs. Good processing aids for natural rubber like LongGreen 12X fix these issues by making natural rubber easier to handle, blending all ingredients well, and making production efficient and consistent.
As top-quality processing aids for natural rubber, LongGreen 12X uses an eco-friendly formula that works well with natural rubber and most synthetic rubbers. It doesn’t affect how fast the rubber vulcanizes, or its strength, wear resistance, or ability to resist aging. Unlike other additives that only do one thing, it helps with mixing, lubrication, flow, preventing sticking, and easy demolding—all in one product. This simplifies the mixing formula, reduces the number of additives needed, and makes production more stable.
When mixing rubber, LongGreen 12X works well as practicalprocessing aids for natural rubber. Fillers like carbon black and silica often clump together, which makes the rubber mix uneven and leads to inconsistent quality between batches. LongGreen 12X soaks into the filler particles quickly, breaks up the clumps, and makes sure all ingredients are spread evenly. This gives a good foundation for the next steps in production and makes the final products more stable in quality.

This versatileprocessing aids for natural rubber also cuts down on mixing time. With the same formula and equipment, mixing takes much less time when using LongGreen 12X. This uses less energy for the mixing machines, which saves money and fits with the industry’s focus on saving energy and being more eco-friendly. It also stops the rubber from getting damaged by over-mixing or overheating, keeping all the good properties of natural rubber.
Rubber sticking to equipment is a big headache in workshops, but as reliable processing aids for natural rubber, LongGreen 12X creates a thin, slippery layer between the rubber and metal equipment. This stops the rubber from sticking, reduces waste and equipment maintenance, and keeps production running smoothly without interruptions.
When making semi-finished rubber products, the advantages of LongGreen 12X as superior processing aids for natural rubber really stand out. Rubber with a lot of fillers—used for tires, hoses, and belts—doesn’t flow well, which makes extrusion and calendering uneven. LongGreen 12X thins the rubber a little, making it flow better. This produces smooth, evenly sized semi-finished products, and more of them pass quality checks.
For transfer and injection molding, professional processing aids for natural rubber like LongGreen 12X let the rubber fill molds faster and with less pressure. This shortens production time, makes more products per day, and reduces defects from molds not being fully filled. It also makes it easier to take vulcanized products out of molds by creating a protective layer, so products don’t get scratched and their sizes stay consistent after cooling.

Real production cases show that LongGreen 12X works well as standard processing aids for natural rubber. In tire production, it makes the tread rubber mix more evenly, works faster, uses less energy, and makes more good tires. In making industrial hoses and sealing strips, it fixes problems with uneven extrusion and rubber sticking, reduces waste, and shortens production time—all without lowering quality.
LongGreen 12X is very versatile. It works with all common types of natural rubber and synthetic rubbers, fits most rubber processing equipment and vulcanization systems, and doesn’t react badly with other common additives. The amount you use is easy to adjust, so technicians can change it based on different production processes, filler amounts, and product needs.
Shenyang LongGreen takes strict quality control measures for LongGreen 12X—every batch is tested many times before it’s shipped to make sure it’s consistent. We also give personalized advice on mixing formulas to help customers get the most out of this high-quality processing aids for natural rubber.
In the competitive rubber industry, choosing efficient, cost-saving processing aids for natural rubber is key to doing well. LongGreen 12X does many things well, gives reliable results, and is good value. It helps factories fix natural rubber processing problems, make production better, save money, and develop steadily in the long run. We welcome rubber manufacturers around the world to learn more about LongGreen 12X and work with us to make the industry better.
