What materials are used to make insulating gaskets? Let’s discuss it together!

　　An insulating gasket is a flexible thermally conductive material that is now widely used to fill the gaps between heating elements and heat‑dissipating components. In addition to enhancing interfacial thermal transfer, it also provides electrical insulation, shock absorption and cushioning, and accommodates dimensional tolerances. Thermal interface pads can effectively increase the heat‑dissipation surface area, thereby achieving excellent cooling performance.

　　What materials are used for insulating gaskets?

　　1. PET insulating gasket

　　The PET film series is dominated by major brands such as DuPont of the United States and Toray of Japan. Thickness typically ranges from 0.025 mm to 0.5 mm, with common colors including transparent, black, semi‑transparent, and milky white. After being die‑cut and formed by specialized manufacturers, these PET insulating sheets are widely used in the electronics, electrical appliances, motor, and telecommunications industries, providing insulation, wear resistance, light shielding, and protective functions across a variety of products.

　　2. Nylon insulating washer

　　Nylon sheets exhibit high tensile strength and impact toughness, excellent wear resistance and lubricity, superior electrical insulation properties, and good chemical resistance. After stamping, these nylon insulating sheets are used in motors, electronic devices, and other applications. They can be custom‑processed into various specifications of dielectric gaskets according to customer requirements, with common grades including PA6 and PA66.

　　3. PC Insulating Gasket

　　PC material exhibits flame retardancy, wear resistance, and oxidation resistance, and these advantageous properties are retained even after die-cutting. Owing to its superior performance characteristics, PC finds a wide range of applications.

　　4. Highland Barley Paper

　　Features: Excellent insulation, flexibility, water resistance, abrasion resistance, oil resistance, and aging resistance; an ideal material for filling gaps. 8. Used as sound‑absorbing and heat‑insulating material in automotive mufflers and exhaust pipes.

Yamagata Optics manufactures shutter blades, apertures, bases, lens barrels, caps, spacers, and camera housings, which can perfectly address image quality issues caused by various types of stray light.

Ultra-Low-Reflectance Coatings for Metal Components Over 99.9% Light Absorption

Inside a lens assembly, reflections from metal spacer rings, lens holder, barrel,spacer , baffle rings and the inner walls of the lens barrel can generate stray light. The resulting artifacts include light streaks, halos, ripple-like patterns and ghost images, all of which degrade image quality, as illustrated.

Serrated-Aperture Diaphragms for Stray-Light Suppression

Yamagata Optical's patented serrated aperture-edge design offers clear advantages over conventional wavy-edge designs. This innovative geometry provides highly effective stray-light suppression. It reflects our long-standing commitment to advancing precision optical components through research and engineering innovation.

Ion Coating Dramatically Reduces Baffle-Ring Reflectance

Yamagata Optical's ion-coating process reduces baffle-ring reflectance by a factor of 8.6. In addition to multiple solutions for suppressing stray light at the aperture edge, we can apply an ultra-low-reflectance ion coating to both sides of the film used to manufacture baffle rings. After treatment, reflectance can fall below 0.3%, substantially improving camera-module optical performance.

Yamagata Optics lens hood ion plating technology

After ion-plating treatment, Yamagata Optics has achieved an 8.6-fold reduction in the reflectance of its aperture. Currently, in addition to multiple anti-glare and stray-light suppression solutions for the inner bore of the aperture, Yamagata Optics can also apply ultra-low-reflection ion-plating to both sides of the raw-material light-shielding film. Following this anti-reflection treatment, the reflectance can be reduced to below 0.3%, significantly enhancing the optical performance of the camera.

The Ultra-Black Revolution in Optics From 5% to 0.1% Reflectance: How Yamagata Optical Is Advancing Photonics

In optical imaging, light can be both essential and disruptive. An unwanted ray may reflect off a lens-barrel wall, scatter from a spacer ring or diffract at a baffle edge. The result can be ghosting, halos, light streaks, ripple-like artifacts or veiling glare that washes out the image. Together, these forms of stray light undermine image clarity, contrast and signal-to-noise ratio.
