In LED optical devices, intelligent car lights, and new display modules, transparent encapsulation adhesive is not only a protective material, but also determines light efficiency, durability, and reliability. Today we are introducing a truly optical grade transparent packaging solution from Elaplus.
——SIPA 3052 optical grade liquid silicone, make your optical module “transparent”!
SIPA 3052 Optical Grade Liquid Silicone – High Transparency Packaging Material Specially Designed for LED Lens Modules.
SIPA 3052 Optical Module Packaging Adhesive
SIPA 3052 is a two-component heat curing transparent silicone gel with excellent optical performance and long-term environmental stability. Specially developed for applications such as LED packaging, car headlight lenses, and optical waveguide modules.
- High transmittance
92%（ 450nm@1mm ）, lighter and more transparent than glass, with a refractive index of 1.45, optimizing light conduction and waveguide efficiency. - Super strong anti yellowing ability
Can resist UV-A/UV-B ultraviolet aging for a long time, without discoloration, stickiness, or fogging under high temperature and high humidity conditions - Excellent modulus control
Shore 00 hardness: 52, providing both support and cushioning, ensuring precise replication of detailed molds.
SIPA 3052 application advantages highlights
Application pain point SIPA 3052 solution
Lens packaging is prone to yellowing and fogging. High purity polysiloxane system, long-term weather resistance without yellowing
Low molding efficiency, poor efficiency 15min@120 Quick demolding at ℃ to improve production line efficiency
Optical component molding is not precise enough, excellent fluidity+mold affinity, perfect molding details
The material is hard and brittle, with a flexible shell structure and low stress curing to protect the device from deformation
The slow curing process at room temperature is unstable and supports 24-hour curing at room temperature, while the thermosetting process is accelerated
