Dotmar Ticomp Family Challenges Teflon in Wear

几乎每个人都听说过Teflon,Teflon是一类专业类PTFE荧光聚合物工程塑料的通用名称,该塑料对人类已知的每种化学物质都具有抵抗力。

特氟龙的壮观物理品质包括像冰那样滑的表面,除非经过特殊治疗,否则不会粘附的物质。

但是Teflon(PTFE的商品名称)只是更广泛的PTFE塑料家族的成员,可以定制成型以提供工业工程师要求的出色工程特征。正如可以混合金属以产生金属合金的金属,并且化学物质合并以创建新化合物一样,因此可以量身定制PTFE,以在特定条件下实现某些高度理想的好处。

One branch of the PTFE family that is especially useful as a bearing and wear surface material is the Ticomp family from our company,Dotmar EPP。这些工程塑料的贵族非常适合整个工业范围的应用,从精致的化学,食品和饮料任务到重量级材料处理,矿物质处理,能源产生,主要加工以及水和废水任务。亚博网站下载

例如,在一个要求最近的澳大利亚应用程序中,在370mm(14.5英寸)直径轴上使用了TICOMP S聚合物,以替代传统填充的Teflon PTFE PTFE旋转密封安排,可在14个大型循环泵上使用澳大利亚使用的大型循环泵。。经过500多个小时的操作后,拆除了Ticomp S密封件并检查。硬钢轴没有标记,密封本身没有变形,也没有密封件上的磨损证据。Ticomp S密封件继续以出色的磨损寿命进行,因此维护关闭较少。

但是,在考虑特定应用程序的Ticomp家族之前,重要的是要知道没有一种理想的PTFE化合物(因为众所周知,每个人都经过量身定制以在特定条件下实现某些好处)。

选择材料的选择应与专家合作亚博网站下载检查(例如Dotmar EPP on www.dotmar.com)但是,从一开始就知道,一系列材料范围包括五种具有特定属性的五种出色材料:亚博网站下载

ticomp s

This material was the result of the search for a material with chemical inertness similar to PTFE, with FDA-approved constituents that offered no formation of debris, low wear, low friction and low abrasion against soft mating surfaces, such as stainless steel.

•出色的磨损特性
•优异的耐化学性
• Constituents FDA approved.
• For high PV and rotary seal application

应用包括泵阀,阀座,旋转密封件,食物和药品剂量密封件,搅拌机轴承和LNG密封件。

ticomp sD

该材料结合了Ticomp S的粘合磨损转移特性,并改善了负载下的记忆力和对变形的抵抗力。(粘合剂磨损是聚合物复合材料在光滑钢上滑动的机制,并且在柜台面上沉积了聚合物的转移层)。

•优异的耐化学性,与Virgin PTFE的耐化学抗性相匹配,对热浓硫酸,热苛性钠和浓硫酸具有出色的耐药性。
• Service temperature under load rated up to 210C, depending on media, loads and speed
• Excellent ductility of the alloy combined with low friction, which optimises adhesive wear resistance

现在,氟聚合物复合材料现在越来越多地用作工程材料或摩擦学特性很重要的应用。亚博网站下载适用于食品的典型产品,包括高值密封,低变形垫和轴承高达240度。

Ticomp BG

This unique synthetic polymer offers

•耐药性良好,类似于Virgin PTFE
• Not abrasive, suited to hard and soft metal counter faces
• Excellent creep and deformation resistance at high temperature
•散发热量
•用于高温抗性的高温应用
需要,例如deckel密封

Applications include gaskets, valve seals (ball and gate), bearings, piston rings – non lubricated, hydraulic/pneumatic seals, Deckel seals and bearing pads. When used as an advanced Deckel seal material for sheet extruders, it offers extended seal life, fewer tool changes and custom dimensions.

Ticomp ht

A newly available synthetic polymer alloy ideal for sealing in high-pressure, high temperature settings that also require low wear and friction.

• Excellent creep and deformation resistance at high temperature
• Chemical resistance similar to virgin PTFE
•散发热量
•也不磨擦,适合硬金属柜台面孔

应用包括垫圈,阀门密封件(球和闸门),轴承,活塞环 - 非润滑,液压/气动磨损带,弹簧加强密封。

SMS300

These specialty formulated polymers offer high strength over a wide temperature range, from -270 C to 275 C with short-term application to 300 C.

•出色的长期稳定性
•高纯度,在真空中低燃气
•出色的电绝缘特性
•出色的耐磨性
• Good chemical resistance
• Low specific gravity

These five Ticomp materials often command a higher price per kilogram than less effective materials, naturally enough. However, this is offset with greatly improved life and performance when correctly specified for a particular application.
