1. Aluminum foil

PE aluminum foil insulation material has a series of superior use characteristics such as super heat preservation, heat insulation, moisture resistance, sound insulation, cushioning, shock resistance, flexibility, light weight, anti-friction, anti-aging, and corrosion resistance.

2. Cellu-cotton

Fiber cotton is a treated polyester chemical fiber material. It is not cotton in the true sense, but it also has a strong warmth retention effect. It is often made into winter cotton clothes, sleeping bags, etc. Fiber cotton is also called four-hole, nine-hole cotton, etc. Basically, the more holes, the better its warmth retention effect. Fiber cotton has low moisture absorption, and the moisture regain of polyester is 0.4% under standard conditions.

3. Elastic cloth

Stretch cloth is a kind of elastic fabric, a kind of knitted fabric with rib structure. Because the loops are intertwined with each other, the yarn will slip when pulled by an external force, so the rib cloth has greater elasticity. By adding a kind of elastic fiber “spandex” to the woven fabric, the fabric woven is also called stretch cloth. Spandex is a very elastic fiber, but the price is relatively expensive. Adding 4%-8% of spandex to the woven fabric can make the fabric have good elasticity.

4. PU leather poly urethane

PU leather is made of woven fabric or non-woven fabric. It has extremely excellent wear resistance, excellent breathability, aging resistance, soft and comfortable, strong flexibility and environmental protection effect now advocated; PU leather is light in weight, waterproof, not easy to expand or deform after absorbing water, environmental protection.
