A PRIMER ON PLASTICS

Brief History of Plastic Injection Molding
by Tom Jorgensen

Modern plastics as we know them today have their origin in the late 19th century when numerous European and American chemists experimented with various types of rubber and residues from chemical mixtures.

In 1865 John W. Hyatt patented a process for combining cellulose nitrate and camphor into a compound he termed "celluloid" which was used as a replacement material for ivory in the production of billiard balls. Celluloid is still used to this day for photographic film used in the motion picture industry.

The first moldable material was introduced in 1907 by Leo Hendrick Baekeland which was a phenolic material he named "Bakelite". Bakelite was such a versatile and durable material that it could be used to produce many useful domestic, industrial and military products. READ MORE

New Plastics Replace Metal

Conductive Compound Ends Aluminum Casting
by Tom Jorgensen

New, high-pressure aluminum compressed gas cylinders are finished in a rigorous washing, coating and curing system. The cylinders suspend from a conveyor by plug hooks that provide a grounding path for the powder coating. Luxfer Gas Cylinders, the world's largest manufacturer of aluminum high-pressure cylinders, reduces costs and lead times for its plug hooks by specifying a conductive RTP Company compound.
