聚氨酯注塑工藝品憑借著自身良好的使用性能而受到用戶的廣泛歡迎，同時(shí)在市面上應(yīng)用越來(lái)越普遍。聚氨酯彈性體是一種介于橡膠和塑料之間的新型高分子合成材料，它既具有塑料的高強(qiáng)度又具有橡膠的高彈性。這類制品硬度范圍較寬，在高硬度下仍具有橡膠的伸長(zhǎng)率和回彈性。而且聚氨酯注塑工藝品還具有較高的強(qiáng)度，因而在受到一定沖擊的情況下仍然能夠保持良好的性能，其沖擊強(qiáng)度和彎曲強(qiáng)的又比塑料高得多。同時(shí)其耐磨性能非常杰出，一般在0.01-0.10（cm3）/1.61km范圍內(nèi)，約為橡膠的3-5倍。而且這類制品屬于強(qiáng)極性高分子化合物，和非極性礦物油的親和性小，在燃料油和機(jī)械油中幾乎不受侵蝕。

Polyurethane injection moulding handicraft is widely welcomed by users because of its good performance. At the same time, it is more and more widely used in the market. Polyurethane elastomer is a new type of polymer synthetic material between rubber and plastics. It has both high strength of plastics and high elasticity of rubber. This kind of product has a wide hardness range and still has the elongation and resilience of rubber under high hardness. Moreover, polyurethane injection moulding crafts also have high strength, so they can still maintain good performance under certain impact conditions, and their impact strength and bending strength are much higher than those of plastics. At the same time, its wear resistance is very outstanding, generally in the range of 0.01-0.10 (cm)/1.61km, about 3-5 times of rubber. Moreover, these products belong to strong polar macromolecule compounds, and have little affinity with non-polar mineral oils. They are hardly eroded in fuel oils and mechanical oils. 聚氨酯注塑工藝品吸振性能優(yōu)良，因而常用于制作各種減振、緩沖類產(chǎn)品。尤其是在模具制造業(yè)中，替代橡膠及彈簧。具有良好的低溫性能。而且聚氨酯耐高能射線的性能很好，在10-10戈輻射劑量下仍具有滿意的使用性能。其還具有良好的機(jī)械加工性能，可采用不同工藝加工。

Polyurethane injection moulding crafts have excellent vibration absorption performance, so they are often used to produce various products of shock absorption and cushioning. Especially in the die manufacturing industry, rubber and spring are replaced. It has good low temperature performance. Moreover, polyurethane has good resistance to high-energy radiation, and it still has satisfactory performance under 10-10 G radiation dose. It also has good machinability and can be processed by different processes.

那么你知道聚氨酯注塑工藝品具體是采用哪些生產(chǎn)工藝嗎？事實(shí)上，聚氨酯是一種高分子材料，它的力學(xué)性能、物理化學(xué)性能十分特殊。選擇不同數(shù)目的官能基團(tuán)和不同類型的官能基、采用不同的合成工藝，從而能制備出性能各異的聚氨酯產(chǎn)品。

So do you know the specific production process of polyurethane injection moulding crafts? In fact, polyurethane is a kind of macromolecule material, its mechanical properties, physical and chemical properties are very special. Polyurethane products with different properties can be prepared by choosing different number of functional groups, different types of functional groups and different synthetic processes.

總的來(lái)說(shuō)，聚氨酯注塑工藝品品類廣泛，產(chǎn)品可包括從十分柔軟到極其堅(jiān)硬的泡沫塑料、耐磨性優(yōu)異的彈性橡膠、高保護(hù)和裝飾性的涂料、高回彈的合成纖維、抗屈撓性能優(yōu)良的合成皮革、粘結(jié)性能優(yōu)良的膠黏劑以及品種多樣、性能優(yōu)異的新型合成材料。

Generally speaking, polyurethane injection moulding crafts have a wide range of products, including foams from very soft to extremely hard, elastic rubber with excellent wear resistance, coatings with high protective and decorative properties, synthetic fibers with high resilience, synthetic leather with excellent flexural properties, adhesives with excellent bonding properties, and new synthetic materials with various and excellent properties.
