Butyrate
Butyrate, as it is commonly known, is a cellulose ester modified by using
butyric and acetic acids producing Cellulose Acetate Butyrate or CAB. Unlike other common synthetic plastics, the cellulosic plastics
are not manufactured by polymerizing a monomer. Instead, they
are produced by the chemical modification of cellulose, a natural
polymer. Cellulose itself is not a thermoplastic, since it will
not melt. Yet , by the viscose process, it is made into film (cellophane)
and into fiber (rayon) that compete with the products of its thermoplastic
derivatives.
Butyrate, cellulose acetate butyrate, tubing is ideal in any length for
storage, packaging and shipping. Tubes are transparent and rigid
with excellent dimensional stability and rigid with excellent
dimensional stability and high impact strength. They are strong,
durable and easy to fabricate. Butyrate tubing can be cut and sawed with standard equipment.
Cellulosics, as a group, are characterized by good strength, toughness,
and high surface gloss. In addition, they have good chemical resistance,
good clarity, sparkle, and will take decoration readily. Cellulose
acetate butyrate is tougher than acetate and has lower moisture
absorption. It resists weathering and has excellent transparency.
Although it is adversely affected by alcohol, alkalis, paint removers,
and acetones, it is resistant to most household chemicals. Additionally,
CAB is resistant to the harmful effects of ultra-violet radiation.
It is used for high gloss vacuum formed faces in back lighted
signs, especially small point of purchase signs. Designers of
display units especially like CAB sheet for its deep-draw properties, ease of formability, and
impact resistance.
Because of its clarity, good impact resistance, ease of fabrication,
and wide range of sizes, CAB tubing is an excellent choice for clear rigid tubing. CAB tubing is widely used in the packaging industry.
