液态硅胶（LSR）射出成型在医疗配件方面的材料选择
据本人跟欧美客户合作过程中的经验体会，医疗用呼吸面罩、喉罩的硅胶部分，大多用液态硅胶射出成型加工，因为液态硅胶在环保安全、品质、外观方面更容易得到保证。

在材料选择方面，大多会选用符合USP CLASS VI SILICONE的材料。

我们在实际中会建议客户使用BLUE STAR Silbione Liquid Silicone Rubber for Health care ( 4330, 4340, 4340FC等）。

BLUE STAR SILBIONE LSR 具有如下特点：
1. SILBIIONE Liquid Silicone Rubbers (LSRs) are two-component platinum-catalyzed silicone elastomers designed for liquid injection molding healthcare and medcial devices, including applications of less than 30 day implantation in the human body.
2. Hardness ranges from 30-70 durometers Shore A
3. Bluestar Silicones's Silbiones LSRs offer the distinctive advantages of easy processing and easy release combined with high performance physical properties.
4. Silbiones LSRs meet or exceed testing requirements of United States Pharmacopoeia (USP) Class VI
Applications:
1.Fabrication of healthcare and medical devices, including less than 30 day implantation
2. skin contact parts like masks or goggles
3.Infant care products
4. Overmolding (Silbione LSR60)
