描述
XIAMETER? RBB-2881-30硅橡膠是一種30硬度的有機(jī)硅橡膠復(fù)合材料，專用于生產(chǎn)模壓制品，效果良好。該硅橡膠能與其它XIAMETER? 品牌有機(jī)硅橡膠混合，所制得的材料具有中等硬度。其外觀呈半透明狀，因此易于著色，形成理想色調(diào)。XIAMETER?RBB-2881-30硅橡膠主要用于模壓制品的生產(chǎn)，如鍵盤、墊圈及其它雜品等，同時(shí)根據(jù)FDA要求規(guī)定，經(jīng)過(guò)合理固化和消毒，該硅橡膠也適用于食品接觸。
應(yīng)用方法
混合或著色適宜采用雙輥開(kāi)煉機(jī)混煉工藝。應(yīng)精確控制混煉時(shí)間，以確保物料混合均勻。模壓成型時(shí)，建議100份原料中加入0.6~1.0份RC-4 （50P）。標(biāo)準(zhǔn)固化溫度為170℃ （338℉），固化時(shí)間取決于終產(chǎn)品的厚度。多數(shù)情況下，應(yīng)在模壓成型后,200℃ （392℉）下二次固化4 小時(shí)。

Specification Writers: These values are not intended for use in preparing specifications.
? XIAMETER RBB-2881-30 Base is a 30 durometer silicone rubber compound especially designed to provide good results when making molded parts. It can be blended ? with other XIAMETER brand silicone rubbers to obtain intermediate hardness. It is translucent, and therefore can be easily pigmented to obtain most any color shade desired. ? XIAMETER RBB-2881-30 Base is primarily used for molded parts such as keypad, gasket, and other miscellaneous goods. It is also suitable for food contact applications when properly cured and cleansed, among others, in accordance with the requirements of FDA regulations.
For blending or pigmenting, milling with two-roll mill is the most suitable process. Milling time should be carefully decided to secure uniformity of materials. When molding, XIAMETER recommends to 0.6 to 1.0 part of RC-4 (50P) to 100 parts of the stock. Standard curing temperature is 170°C (338°F), and its cure time depends on the thickness of final products. Post cure condition would be 4 hours at 200°C (392°F), after molding in most cases.
