Properties Of Shoe Sole Materials For Commonly Used Labour Safety Shoes

One

Hot pressed plastic molding, divided into natural rubber and synthetic reclaimed rubber.

Good abrasion resistance, skid resistance, good elasticity, no breakage, good softness, good elongation, stable shrinkage, good hardness, good bending property and waterproof.

2.TPR bottom: TPR

Special material is a new type of polymer shoe material which is mainly produced by thermoplastic SBS. It has the properties of rubber and can be processed and recycled by thermoplastics. It is more wearable, easy to shape and cheap. The safety shoes made of TPR bottom materials are characterized by light weight, comfort, high elasticity, easy to stain, good ventilation and high strength, especially low temperature resistance, high friction coefficient and strong grip.

But contact with oil solvents will slip.

3. polyurethane floor: it is a kind of polymer material, which is made from A/B/C polyester resin, which is divided into two types: oil and water.

It is a new organic polymer material, which is used to produce high-grade leather shoes, sports shoes, travel shoes and labor safety shoes.

It has excellent abrasion resistance and repeated bending properties, good tear strength and elasticity, excellent oil resistance, acid resistance, alkali resistance and low temperature resistance, low density, soft texture, good elasticity, comfortable and light wearing, good oxidation resistance and hardness, excellent shock absorption and skid resistance, good chemical resistance, corrosion resistance and environmental protection, and is not easy to wrinkle.

The waste PU bottom can be automatically degraded, which is environmentally friendly. It is more suitable for the thick sole shoes that require impact resistance and wear resistance. It is one of the most commonly used sole soles for shoes.

4.TPU bottom: it is a linear polymer material produced by reaction of diisocyanate and macromolecular polyols and chain extender. It is a new environmental protection material.

TPU bottom made shoes have excellent mechanical strength, wear resistance, oil resistance and flexural resistance, especially wear resistance is the most outstanding, good appearance, generous high-end.

5.TR bottom: TR

It is a new product which is improved on the basis of TPR. It is a synthetic material of TPE and rubber. The product has more excellent performance of various indicators.

The labor insurance shoes made of TR bottom are characterized by many appearance, good handle, bright color, high finish, high technology content, and can be recycled by 100%. It belongs to the environmental protection sole material.

6.EVA bottom: polymer materials, light, elastic, flexible, and not wrinkled, with excellent coloring, suitable for all kinds of climates and easy to process. The more EVA contains vinyl acetate, the better the elasticity of safety shoes.

7.MD bottom: disposable foam molding by EVA. It has good softness, high elasticity, good thermal insulation performance, light weight, elasticity, fine appearance and easy cleaning. MD bottom shoes have good hardness, density, tensile force, tear and elongation.

Generally, high shoes are more suitable.
