Product Description

I. Product Overview

1. Material: 50 Shore A Medical-Grade Silicone

It features moderate hardness, balancing structural support, shape retention and soft conformability. It will not deform from excessive softness and can maintain the strip-shaped structure of the product. Meanwhile, it is not overly rigid to irritate the skin, causing no compression discomfort where it contacts the human body.

Compliant Biocompatibility

It has passed safety tests for medical silicone, featuring non-irritating and non-sensitizing properties. Long-term contact with skin or wound peripheries will not trigger redness or itching, making it suitable for medical care and body surface fixation applications.

Stable Physical & Chemical Properties

It withstands high and low temperatures and aging. It resists cracking and pulverization after repeated bending and long-term adhesion. Being hydrophobic and water-repellent, it resists mold and bacterial growth after exposure to sweat or disinfection wipes, allowing easy cleaning and sanitization. It is insulating, odor-free, and free of harmful leachables such as phthalates and heavy metals, complying with environmental standards for medical materials.

2. Adhesive Substrate: Authentic 3M Double-Sided Pressure-Sensitive Adhesive

Formulated for strong bonding with silicone surfaces, it solves the common challenge of poor silicone adhesion and leaves no adhesive residue upon peeling.

Core Adhesive Performance

Balanced tack: Delivers consistent adhesion to plastics, metals, human skin, fabrics and panels at room temperature, resisting detachment during routine fixation. It peels off gently without pulling or damaging skin or painted surfaces.
Environmental resistance: Offers moisture and sweat resistance. Its adhesion does not degrade rapidly under sweating or slightly humid conditions. The thin adhesive layer adds negligible thickness and preserves overall flat conformability.
Release liner protection: The backing adhesive comes with an anti-stick release liner that blocks dust during production and storage. Simply peel off the liner for quick, convenient application.

III. Production Process

1. Compression Molding & Vulcanization Process

Special medical flat vulcanizing machines are adopted with precisely calibrated temperature, time and pressure parameters. The silicone body is integrally molded under high temperature and high pressure, which ensures uniform internal molecular structure of the silicone, consistent and stable Shore A 50 hardness, and eliminates defects such as air bubbles, delamination and material shortage.

Molds are regularly disassembled, cleaned and disinfected with medical alcohol to prevent residual grease on molds from contaminating the silicone contact surface. The finished silicone product is free of burrs and sharp edges to avoid skin scratches during use.

2. Lamination of 3M Medical Double-Sided Adhesive Backing in Dust-Free Environment

The adhesive lamination process is carried out at independent Class 1,000 dust-free workstations. Operators are required to wear dust-free suits, dust-free gloves, masks and shoe covers; direct bare-hand contact with the silicone bonding surface is prohibited.

The equipment is equipped with electrostatic dust removal devices to automatically blow off fine dust on the silicone surface before lamination. This achieves complete seamless bonding between the adhesive layer and silicone without air bubbles, wrinkles or edge lifting, and guarantees stable adhesion performance.

3. 100% Full Inspection in Class 100,000 Dust-Free Workshop
All finished products are uniformly transported to a Class 100,000 medical cleanroom for 100% full inspection.

IV. Product Application Scenarios
This light-guiding silicone component for signal acquisition of biofeedback devices is manufactured via compression molding with light-transmissive medical-grade silicone, specially designed to match electroencephalogram (EEG) / physiological feedback therapy headbands.

Precise Feedback

The device is equipped with forehead indicator lights for visual real-time feedback, enabling users to instantly perceive their training status.
Optical PerformanceIt features high light transmittance and uniform light diffusion, eliminating light spot distortion. This allows the device to accurately capture human biological signals and supports psychological and physiological regulation therapy through biofeedback treatment.
Application ScopesIt serves as a matching accessory for biofeedback rehabilitation treatment instruments targeting depression, insomnia and anxiety disorders. It delivers a stable light-transmitting sensing foundation and supports mass production, customization and development of related equipment.
