1. Introduction
Slip inhibitor is widely used in EVA foam bottom, improve the wear resistance of materials, and widely used in PR PE, HDPE, and another injection molding, as a lubricant flowing agent.
It is a white viscous liquid solution, with high viscosity. It can be applied to different surfaces to reduce wear and tear caused by friction. The slip-inhibitor can also be sprayed on other materials to prevent them from sticking together or slip off.
It is frequently used in EVA foam bottom to improve the wear resistance of materials such as rubber, PP and PVC materials (especially PP).
It can also be sprayed on HDPE material for the same purpose.
2. What is a slip inhibitor?
A slip inhibitor is a non-stick coating, which can be applied to products to improve its wear resistance. Slip inhibitors are widely used in EPAs, and they are also used in injection molding, plastic injection molding, thermosetting resin and other materials. They are widely used in food packaging, such as ice cream and baked goods.

Slip inhibitors are widely used in EPAs, and they are also used in injection molding, plastic injection molding, thermosetting resin and other materials. They are widely used for food packaging – ice cream and baked goods
Slip inhibitors have been widely used for years for many applications like ice cream packaging; it has been reported that the NST slips from the polypropylene / polyethylene film of PP/PE film was between +30% to +60% compared with the slip resistance of NST (i.e., “slip” or “slip-thickness”) of different PTFE based coatings in terms of APC value (Ashley et al., 1996).
The polypropylene/polyethylene film of PP/PE film was between +30% to +60% compared with the slip resistance of NST (i.e., “slip” or “slip-thickness”) of different PTFE based coatings in terms of APC value (Ashley et al., 1996). Polypropylene/polyethylene films exhibit higher impact strength than their equivalent Teflon sheets due to excellent deformation behavior at high temperature. Non-stick coatings results in low friction or low coefficient of friction (CFR) due to well developed scratch resistance characteristics . The smooth surface feature is produced by well developed scratch properties . Further improvement on this performance can be achieved by adding metal additives such as zinc or titanium . Such additives reduce the adhesion between metal particles [which] improves the wear resistance . Furthermore , metal additives can also help improve wear resistance by improving chemical compatibility with rubber matrix materials [which] enhances rubber matrix’s ability to resist cracking during repeated use.
The above is just one way of doing it; there are other ways too:
- using an effective lubricant spray
- using a coating that may contain metal oxides such as TiO2 , Al2O3 , ZnO etc.; ZnO
3. The use of slip inhibitor
Slip inhibitor is widely used in EVA foam bottom , improve the wear resistance of materials, and widely used in PR PE, HDPE, and another injection molding, as a lubricant flowing agent. Slip inhibitor is an additive used to enhance the flowability of polyurethane foams . It has been used for high-pressure applications. Injection molding (IM) is a process by which polyurethane (PU) foams are molded on one or more molding dies. The foams are injected into the injection die cavity with a liquid or gaseous fluid . Surfaces that are coated with slip inhibitors gain greater surface-to-volume ratio during injection and undergo less stress than their uncoated counterparts. Slip inhibitors have also been found to reduce shrinkage during injection pressure cycles.
Injection molds have become increasingly popular since their introduction in China in the late 1990s due to their higher output and ease of use compared to other molding processes, among other advantages. As part of a stable environment that promotes stability and reliability , slip inhibitors play an important role in establishing safety standards for injection molds. Slip inhibitors have been successfully incorporated into many types of polyurethane foams such as polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), polychloroprene (PCT), styrene – butadiene rubber (SBR), styrene – acrylonitrile butadiene styrene copolymer(SAN) – styrene acrylic acid copolymer(SAA), with good performance properties .
4. The benefits of slip inhibitor
slip inhibitor is not a single thing. It is a group of substances that are used as lubricants in injection molding, and it is usually applied at the top of the E-layer set, which makes it wipe out during the first pass. More than that, slip inhibitor can also be used to apply a slip layer on products (which is usually applied on the bottom side).
But from different uses, slip inhibitor can be divided into three parts:
- The lubricant for injection molding (E-layer)
- The lubricant for manufacturing (bottom side)
- The slip layer (top side)
It has been widely known that slip inhibitor can improve the wear resistance of materials, and it has also been widely known that it can also be used as a lubricant for manufacturing products such as PE, HDPE and other injection molding materials. However, some people still haven’t found out how to use slip inhibitor to improve their products’ wear resistance or their manufacturing process efficiency; they just have to rely on their own thoughts or theories about them. We will explain how slip inhibitor can be effectively used in EVA foam bottom with our experience; how it will affect product performance and improve production efficiency; and how we see that application in future development based on our research now and what we expect for the future of this product development technology.
5. The drawbacks of slip inhibitor
Slip inhibitor is a non-toxic lubricant for lubricants, and is widely used in EVA foam bottom, improve the wear resistance of materials, and widely used in PR PE, HDPE and another injection molding, as a lubricant flowing agent.
Despite its great benefits to the market, slip inhibitor has some drawbacks. First of all, it can have a bad odor and make the product sticky. Second, slip inhibitor can be very expensive . Like many other lubricants it is also flammable at high temperatures so it is not suitable for use in high temperature applications like car engines or machinery.
6. Conclusion
Thanks for joining us. Hope you learned something. For the next episode, let’s talk about how to use this knowledge to your advantage when it comes to your product launch. What is slip inhibitor? What are the benefits of it for you?
This is another one of those products that was just recently released and looks great on paper, but in reality — doesn’t actually provide any real benefit at all. This is also one of those products where the hype is hard to separate from the product itself:
It’s a broad brush, but I think one of the reasons that so many old product launches are forgotten (or not remembered at all) is because they’re just mediocre products. It’s not a bad idea if you can sell it, but it’s not really a good idea if you can’t do so. I’ll be speaking more about that in upcoming episodes.
