TAC Film Market Growth, Trends and Investment Feasibility Analysis Report 2020 by Million Insights
The Global TAC(Tri-acetyl Cellulose) Film Market is segmented on the basis of types,
application, and geographical region. TAC stands for tri-acetyl cellulose, also
known as triacetate, CTA, Cellulose triacetate. It is a chemical compound
manufactured from cellulose and a source of acetate esters, characteristically
acetic anhydride. It is classically used for the creation of fibers and film
base. The TAC film is a polymeric film in which all or a predominant portion of
the film is cellulose triacetate. Tri-acetyl cellulose (TAC) films are widely
used as a protective film for polarizers because it has high light
transmittance, low birefringence, high moisture permeability, high uniformity
and good curling property.

Plasticizing
agents have long been known to increase the physical properties of solvent cast
cellulose triacetate (also called triacetyl cellulose or TAC) polymeric films.
TAC polymers have a cellulose chain backbone with varying degrees of
acetylation. TAC can range in substitution from approximately 2.4 to 3 acetyl
substitution points on the cellulose backbone. Other substitutions on the
cellulose backbone could be hydroxyl, propyl or butyl groups. TAC tends to be
high in polymer molecular weight. This is due to the enormously large cellulose
chains it is formed from. TAC cannot be thermally extruded, as it does not
possess a melting point. TAC is a very good polymer for forming amorphous
polymer sheet.
The TAC film
plays an active role in optical compensation of LCDs as well as protection of
polarizers. Additives can control the out-of-plane birefringence of the TAC
film, and the in-plane birefringence can be controlled by stretching. Coating a
discotic material on the TAC film gives a supplementary optical compensation
layer. On the basis of product types, the global market is classified into
Thickness 50μm, 80μm, Thickness ranges from 80μm, 90μm, 150μm, 190μm, 240μm to
270μm, Thickness of 30μm, 40μm.
On the basis of
applications, the global market is classified into TAC film for Polarizer (UV
type and normal type), TAC film for polarized sunglasses (with color or clear),
TAC film for insulation (with UV and without UV), photographic equipment
filters, anti-glare goggles, onboard vehicle navigation systems, as well as
optical eyepieces and lenses for polarizing microscopes and special medical
purposes. Geographically, the global market is segmented into North America,
China, Europe, Southeast Asia, Japan, and India. The key players in the TAC
film market include Fujifilm, Konica Minolta, Zeon, Tac Bright Optronics Corp.,
HYOSUNG, IPI, Lucky Group and Skinnovation.
