聚氨酯緩沖塊是彈性體中比較特殊的一類，其原材料品種繁多，配方多種多樣，可調(diào)范圍很大。聚氨酯緩沖塊硬度范圍很寬，低至shore A10以下的低模量橡膠，高至shore D85的高模量、抗沖擊的彈性材料。所以聚氨酯彈性體的性能范圍很寬，是介乎于從橡膠到塑料的一類高分子材料。聚氨酯緩沖塊按其制品加工方法可分為澆注型、熱塑性和混煉型三大類。我們主要所做的CPU它是在加工成型前為粘性的液體，其制品成型即可加壓硫化游客常壓硫化；即可熱固化又可常溫固化；即可手工澆注又可用機(jī)器連續(xù)澆注成型，所以澆注成型的適用于大、中、小型彈性體制品的生產(chǎn)。

Polyurethane buffer block is a special kind of elastomer. It has a wide range of raw materials, formulations and adjustable range. The hardness range of polyurethane buffer block is very wide, low modulus rubber as low as shore A10, high modulus and impact resistant elastic material as high as shore D85. Therefore, polyurethane elastomer has a wide range of properties, which is a kind of macromolecule material ranging from rubber to plastics. Polyurethane buffer blocks can be divided into three types according to their processing methods: casting type, thermoplastic type and mixing type. The CPU we mainly made is a viscous liquid before processing. Its products can be vulcanized under pressure by tourists at atmospheric pressure. It can be cured by heat and at room temperature. It can be manually poured and continuously poured by machines. Therefore, the pouring process is suitable for the production of large, medium and small elastic products. 

聚氨酯緩沖塊具有高強(qiáng)度、高耐磨、耐油、吸振力強(qiáng)等特點(diǎn)，廣泛應(yīng)用于重型機(jī)械的減振板、沖裁、沖壓、板金校型及對絕緣要求較高的領(lǐng)域。它在高硬度下仍具有橡膠的伸長率和回彈性。

Polyurethane cushion block has the characteristics of high strength, high wear resistance, oil resistance and strong vibration absorption. It is widely used in the fields of shock absorber plate, blanking, stamping, sheet metal calibration and high insulation requirements for heavy machinery. It still has the elongation and resilience of rubber at high hardness.

聚氨酯緩沖塊在橡膠硬度下它們的扯斷強(qiáng)度和承載能力比通用橡膠高得多。在高硬度下其沖擊強(qiáng)度和彎曲強(qiáng)的又比塑料高得多。其耐磨性能非常杰出，一般在（cm3）/1.61km范圍內(nèi)，為橡膠的3-5倍。

Polyurethane buffer blocks have much higher breaking strength and load-carrying capacity than general rubber under rubber hardness. At high hardness, the impact strength and bending strength are much higher than those of plastics. Its wear resistance is very outstanding, generally in the (cm3) / 1.61km range, 3-5 times as much as rubber.

聚氨酯緩沖塊是一種強(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。同時(shí)還有高耐氧化性，吸振性能優(yōu)良，可做減振、緩沖作用，良好的低溫性能、耐輻射性能；良好的機(jī)械加工性能。

Polyurethane buffer block is a kind of strong polar macromolecule compound with low affinity to non-polar mineral oil, which is hardly eroded in fuel oil and mechanical oil. At the same time, it also has high oxidation resistance, good vibration absorption performance, can be used as shock absorption and buffer, good low temperature performance, radiation resistance, and good machinability.
