ELASTOSIL® LR 3170/40 A/B
Self-adhesive liquid silicone rubbers of the ELASTOSIL® LR 3170 series are paste-like, low inflammable two-component compounds with extremely short curing times. Their vulcanizates are noted for excellent mechanical and electrical properties.
特性
ELASTOSIL® LR 3170 series are primerless, selfbonding grades that adhere to various plastic substrates (e. g. PA, PET, PBT) and metals, but not in the mold. The bonding is improved by a subsequent heat treatment process (e. g. one hour at 100 °C) or by a longer storing at room temperature. Because of the individual surface properties each substrate must be tested before mass production. For further information on tested material combinations please refer to the corresponding adhesion tables which are available upon request from the responsible sales manager.
The excellent flame retardancy is confirmed by achieved UL94-V0 listings at 3mm thickness. Good heat resistance as well as short curing times and non abrasive behaviour in LIM process are further benefits of this material.
ELASTOSIL® LR 3170/40 A/B的特殊性能
- 减少挥发物含量
- 自粘性
- 阻燃性
ELASTOSIL® LR 3170 series are particularly suitable for the economical production of large series of overmolded parts (thermoplastic/elastomer), even in a comolding process (shuttle mold) under standard conditions, without any special treatment of the mold surface.
Parts made from ELASTOSIL® LR 3170 can generally be used for technical applications without post-curing, but do not comply with regulations concerning use in the pharmaceutical and food industry.
The A and B components are delivered ready to use in 20 kg pail and 200 kg drum kits. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by a static mixer. The mixing ratio is 1 : 1.
Note: Start-up of new molds should be supported by use of ELASTOSIL® AUX Mold Release Agent 32.

包装
This product is available in 20 kg pail and 200 kg drum kits.
储存
Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
