Color Filter

Color-Correcting Filter Sheets with Silicone’s High Resilience

Known by many names such as “[transparency] color film”, “[color] film wrap”, “lighting film”, or “gels” in stage lighting, color filters adjust the color of light by selectively allowing differing wavelengths of light to pass through at varying ratios.

Choose from our standard selection, or consult with us to customize your own color.

An inherent consequence of the filtering action is the absorption of energy into the substrate.

Asahi Rubber color filters are unique in that the filtering substrate is silicone rubber, which is extremely resilient to high levels of short wavelength light energy and heat energy. These silicone color filters are long-lasting and resistant to fading.

Construction and Shape Customization

Asahi Rubber color filters come with protective PET film backing on both sides for stiffening and dust resistance.

The PET backing is optionally user-removable for higher transparency (see below for data) and higher heat/UV resistance. *not reattachable

PET max temp: 80°C

Silicone max temp: 180°C (recommended operating temp ≤100°C)

Ensure appropriate separation from light source considering temperature.

Standard sizes are 100×100mm, 300×500mm, and 300mm×50m (roll).

With PET backing attached, filter sheets can be easily cut to desired shape. Optionally, Asahi Rubber can deliver custom pre-cut pieces in higher volumes.

Mounting can be done mechanically or by adhesion, in the same manner as common cellophane filters.

Use an acrylic tape with PET film, or a silicone-compatible adhesive tape without.
