超高分子量聚乙烯的特点:

1、超高分子量聚乙烯板耐磨耐损,且分子量越大,材料的耐磨性和抗冲击性越高;用于好多的机械轨道。

2、超高分子量聚乙烯板的冲击强度是现存塑料中的高值,即使在70℃时仍有荒谬高的冲击强度;

3、自润滑;

4、吸水率极低。因此,其物理机械性能与使用的职责条目中的湿度身分无关;

5、超高分子量聚乙烯板化学性褂讪,在一定的温度,浓度限制内能耐酸、碱、盐等多样腐蚀性介质及有机溶剂的腐蚀;

6、超高分子量聚乙烯板无味、无毒、无嗅,本身无腐蚀性,具有生理轮回性和生理安妥性.

7、不粘附性;

8、高密度聚乙烯分子量普及50万时, 激情脆化温度降至140℃。超高分子量聚乙烯致使不错在液氮作用下,其使用温度可达269以下℃,仍有一定的机械强度。

UHMWPE board is more wear-resistant than other materials, including metal, nylon, polyurethane and fluoroplastics. This is an extremely tough plastic with high wear resistance and abrasion resistance. The versatility of polyethylene makes it a popular plastic in numerous industrial applications requiring durability,久久精品人人爽人人 low friction and chemical resistance. UHMWPE board is easy to manufacture and process

Properties of UHMWPE:

1. The UHMWPE sheet is wear-resistant and wear resistant, and the higher the molecular weight is, the higher the abrasion resistance and impact resistance of the material are; Used for many mechanical tracks.

2. The impact strength of UHMWPE sheet is the highest among the existing plastics, even at 70 ℃, it still has quite high impact strength;

3. Self lubrication;

4. Very low water absorption. Therefore, its physical and mechanical properties have nothing to do with the humidity factor in the working conditions;

5. Ultra high molecular weight polyethylene sheet is chemically stable, and can resist the corrosion of various corrosive media such as acid, alkali, salt and organic solvent at a certain temperature and concentration range;

6. UHMWPE sheet is tasteless, non-toxic, odorless, non corrosive, and has physiological circulation and physiological adaptability

7. Non adhesion;

8. When the molecular weight of HDPE exceeds 500000一级香港a裸毛片, the embrittlement temperature drops to 140 ℃. UHMWPE can even be used under 269 ℃ under the action of liquid nitrogen, and it still has a certain mechanical strength.
