What are the disadvantages of Bakelite?

What are the disadvantages of Bakelite?

However, bakelite had its obvious limitations: it was resistant, but fragile. The hardness and lack of flexibility that made it suitable for certain uses was a drawback for others. “You couldn’t make packaging from Bakelite, or fabric, or anything transparent, super lightweight things,” Freinkel sums up.

Why is Bakelite not made anymore?

Bakelite applications in conservation were discontinued in the 1940s because of certain disadvantages that soon became apparent. The lack of records and relevant information precludes any assumption on the extent of its use and in which institutions.

What is the difference between Bakelite and melamine?

The key difference between bakelite and melamine is that bakelite is a thermosetting phenol-formaldehyde resin whereas melamine is an amine organic compound. Bakelite is a thermosetting plastic.

Is Bakelite and phenolic the same?

Bakelite Phenolic is produced in dozens of commercial grades to meet mechanical, electrical and thermal requirements. Bakelite is a generic named material based on the thermosetting phenol formaldehyde resin polyoxybenzylmethylenglycolanhydride, developed in 1907-1909 by Dr.

Why is Bakelite useful?

Bakelite has a number of important properties. It can be molded very quickly, decreasing production time. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It is also resistant to electricity, and prized for its low conductivity.

What is the melting point of Bakelite?

It is made with metallocene catalyst technology This plastic has the highest melting point (518F) (270C) of any styrenic homopolymer. It also has high chemical, water, and steam resistance, exceptional electrical properties, and well-balanced impact resistance and stiffness. What are the Bakelite temperature limits?

What’s the difference between Bakelite and plastic?

Bakelite is different from other plastics due to its unique properties. The key difference between Bakelite and plastic is, Bakelite is the first synthetically produced thermosetting plastic with heat resistant and non-conductivity of electricity.

Can you melt Bakelite?

R. It can be melted again and again without any change.

What are uses of Bakelite?

1. Bakelite is a good insulator used in non-conducting parts of radio and electric devices like switches, automobile distribution caps, insulation of wires, Sockets, etc. 2. It is used to make clocks, buttons, washing machines, toys, kitchenware, etc.

What are the uses of Bakelite and melamine?

Bakelite:It is a very hard and tough plastic.It is a poor conductor of heat and electricity. Melamine is a plastic which can tolerate heat better than other plastics and resist fire. It is used for making floor tiles,unbreakable kitchenware,ashtray and fire resistant fabric.

What is the formula of Bakelite?

Bakelite

Which type of polymer is Bakelite?

thermosetting polymer
What is Bakelite? Bakelite is a polymer made up of the monomers phenol and formaldehyde. This phenol-formaldehyde resin is a thermosetting polymer.
