The reason why the punch jacket can become the first choice of outerwear for all outdoor enthusiasts is determined by its all-weather function. It was first used for the final rush when climbing high altitude snowy mountains with 2~3 hours away from the summit, at which time it would take off the down jacket, unload the big backpack, and only wear a lighter garment to move forward lightly.

SILIKE Si-TPVs Overmolding can adhere to other materials through injection molding. suitable for insert molding and or multiple material molding. Multiple material molding is otherwise known as Multi-shot injection molding, Two-Shot Molding, or 2K molding.
SI-TPVs have excellent adhesion to a variety of thermoplastics, from polypropylene and polyethylene to all kinds of engineering plastics.
When selecting an Si-TPV for an over-molding application, the substrate type should be considered. Not all Si-TPVs will bond to all types of substrates.
For more information regarding specific over-molding Si-TPVs and their corresponding substrate materials, please feel contact us.
Si-TPV Modified soft slip TPU granules are an innovative approach for manufacturers of Outdoor Jackets who require unique ergonomic designs as well as safety, waterproofing and durability.
First of all, we have to understand how the punching jacket is working, this depends on the composition of the structure of the punching jacket. The biggest role of the jacket is waterproof, windproof, plus moisture permeability and breathability.
The most important thing here is the waterproof function, so how does the punching jacket do waterproof? This is to start from the waterproof fabric.
Punching jacket fabric classification
There are mainly the following waterproof fabrics for punching jackets:
★PU coating
PU coating, is a hydrophilic fabric, the main component is polyurethane, soft touch, very good elasticity, more wear-resistant, can do a very thin coating, but water vapor can not pass through, so the permeability is poor. And with the increase of time, the waterproof effect will become worse, and it will also become hard in the case of low temperature. Characteristics of the punching jacket with this fabric are that it is inexpensive.
★Waterproof film E-PTFE
E-PTEE compound membrane is made of polytetrafluoroethylene as raw material by expanding and stretching the formation of porous membrane. Experiments have found that the PTFE membrane surface is covered with original fiber-like microporous, each square inch has up to 9 billion microporous. Its windproof principle is because of the microporous membrane structure arranged in a disorderly manner, there is no wind through the film through the required single-direction channel, the wind in the film surface formation of scattering, and thus can not pass through the labyrinth of the film structure. The size of the pore size of the microporous membrane is about one twenty-thousandth of a drop of water, so it can block the entry of raindrops, and at the same time is 700 times larger than a water molecule, so it does not hinder the evaporation of sweat discharge, which makes it waterproof, windproof, and dry and breathable.
★TPU fabric
TPU composite fabric has always been the preferred fabric for outdoor apparel due to its excellent performance, TPU fabric is a composite material formed by using TPU film or TPU Elastomeric Materials laminated on various fabrics and combining the characteristics of both, TPU fabric has the superior characteristics of good elasticity, toughness, abrasion resistance, good cold resistance, environmental protection and non-toxicity.
