PolyBlend? 1100-55A
热塑性聚氨酯弹性体合金
AdvanSource Biomaterials Corp.
产品说明：
PolyBlend is a family of exceptionally soft, aromatic polyurethane elastomeric alloys, which can be used as a substitute for natural rubber or latex in many applications.
These polymers encompass unique characteristics such as low flexural modulus, moderate tensile strength, and high elongation, in addition to allowing for a high draw-down ratio due to its superior melt strength and chemical integrity.
PolyBlend can be processed on conventional extrusion or injection molding equipment and is available in hardnesses ranging from 45 Shore A to 80 Shore A.
AdvanSource Biomaterials synthesizes and manufactures medical grade materials offering the ability to tailor physical and mechanical characteristics to support and enhance your end product design.
These mechanical characteristic's, critical to the design and development of medical devices, can incorporate a wide range of physical and chemical properties while maintaining core characteristics such as biodurability and biocompatibility. In most materials, specialized characteristics such as the addition of colorant agents or antimicrobial properties (where applicable) can be added to the polymer to provide a homogenous material and limit secondary processing steps.
In addition, radiopaque agents may also be incorporated into the formula to provide additional product enhancements and may contain up to 40%, by weight, of a radiopaque agent thus allowing varied-scale visibility options.

TPU(Thermoplastic polyurethanes)名称为热塑性聚氨酯弹性体橡胶。主要分为有聚酯型和聚醚型之分,它硬度范围宽(60HA-85HD)、耐磨、耐油,透明,弹性好,在日用品、体育用品、玩具、装饰材料等领域得到广泛应用,无卤阻燃TPU还可以代替软质PVC以满足越来越多领域的环保要求。
所谓弹性体是指玻璃化温度低于室温度,断裂伸长率50%,外力撤除后复原性比较好的高分子材料。聚氨酯弹性体是弹性体中比较特殊的一大类,聚氨酯弹性体的硬度范围很宽,性能范围很宽,所以聚氨酯弹性体是介于橡胶和塑料的一类高分子材料。
可加热塑化,化学结构上没有或很少交联,其分子基本是线性的,然而却存在一定的物理交联。这类聚氨酯称为TPU
特性
1、耐磨性能
当材料在使用过程中经常受摩擦、刮磨、研挫等机械作用,会引起其表面逐步磨损,因此材料的选择磨耗性显得非常重要。TPU塑胶原料耐磨性能优异,较天然橡胶耐磨五倍以上,是耐磨制品*的材料之一。
2、拉伸性能
拉伸强度高达70MPa ,断裂伸长率可高达1000%。
3、撕裂性能
弹性体在应用时由于产生裂口扩大而使之破坏称为撕裂,撕裂强度就是材料抵抗撕裂作用的能力;一般而言TPU具有较高的抗撕裂能力,撕裂强度与一些常用的橡塑胶比较是非常优异的。
4、屈折性能
很多塑胶材料在重复的周期性应力作用下容易产生断裂,TPU制品在不同环境下都可以保持*的耐屈折特性,为高分子材料中*选择之一。
5、耐水解性能
TPU在浑浊下耐水性能是良好的,1~2年内不会发生明显水解,尤其以聚醚系列更佳。聚酯系列在50℃的水中浸泡半年或70℃浸泡3周或100℃浸泡3~4天,会完全分解,这是TPU适合作为环保材料的原因之一,需经常性与水接触之产品,则建议使用聚醚系列。
6、抗高温与抗氧化性能
一般的塑胶原料长期在70℃以上的环境下容易氧化,TPU抗氧化能力良好;一般而言TPU耐温性可达120℃。
7、耐油与耐药品性能
TPU为一种强极性的高分子材料,和非极性矿物油的亲和性很小,在燃料油(如煤油、汽油)和机械油(如液压油、机油、润滑油等)中几乎不受侵蚀;其中,TPU产品中又以聚酯系列的产品耐油性较佳;TPU薄膜及片材对于油脂的体积变化很小,抗张强度甚至比原初始值更高;需要注意的是在矿物油中若含有少量的水分时,会对薄膜物性产生不同程度的负面影响。
8、低温性能
TPU有非常好的耐低温性能,通常能达到-50℃,可取代一般PVC因低温脆化而无法应用的各个领域,特别适合用在寒带相关的种类制品。
9、气密性
TPU非常容易利用高周波或是热压来熔接,因此广泛应用在充气制品上。气体系数是指在一定温度和压力下,气体透过试样规定面积的速率,同一材料对不同气体的透过率有时差异很大。一般来说,聚酯系列制品气密性比聚醚系列更好。
10、生物医学性能
TPU具有*的生物相容性、无毒、无性、无局部刺激性、无致热源性,因此广泛应用在医疗、卫生等相关产品以及运动、保护器材上。[1]
TPU塑胶原料应用范围
TPU已被广泛应用于:鞋材、成衣、充气玩具、水上及水下之运动器材、医疗器材、健身器材、汽车椅座材料、雨伞、皮箱、皮包等。
TPU薄膜在运动鞋上应用极广泛:鞋底及鞋面上的商标装饰、气囊、气垫、油包等。而今,TPU薄膜在运动鞋上应用又有两种趋势:
一是由耐克运动鞋所刮起的流行风,即是将TPU薄膜先网版印刷上色,再以高周波成形并粘合在鞋面上做装饰,以取得特殊的装饰效果。
