LSR Injection Molding Materials
Standard LSR
Medical LSR is very suitable for injection molding as it meets biocompatibility requirements (e.g., USP Class VI) and is safe for use in medical applications. It is utilized across the board in catheters, implants, and respiratory masks because of its non-toxicity and sterilization for compatibility.
- Mill Lead Time: Up to 5 days
- Color: Clear, white, black
Medical-Grade LSR
Medical LSR is very suitable for injection molding as it meets biocompatibility requirements (e.g., USP Class VI) and is safe for use in medical applications. It is utilized across the board in catheters, implants, and respiratory masks because of its non-toxicity and sterilization for compatibility.
- Mill Lead Time: Up to 7 days
- Color: Clear, white, blue
Food-Grade LSR
Food-grade LSR is injectable into mold because it meets LFGB and FDA requirements, rendering it safe for food contact. It is used in baking molds, bottle nipples, and food seals owing to its heat-stable and non-toxic nature.
- Mill Lead Time: Up to 6 days
- Color: Clear, white
High-Transparency LSR
High-transparency LSR is appropriate for injection molding where optical clarity and UV resistance are required. It is widely utilized in optical lenses, clear seals, and trim components for appearance and performance.
- Mill Lead Time: Up to 7 days
- Color: Clear
Flame-Retardant LSR
Flame-retardant LSR finds the best application in injection molding for electronics and semiconductor applications on the basis of its UL 94 V-0 rating. It is applied extensively to insulation of wires, electrical seals, and connectors owing to its fire-resistant feature.
