Question 1

What is engineering plastics

Accepted Answer

Engineering plastics are plastic materials with high mechanical strength and proper balance. It means that all mechanical properties, such as high tensile strength, bending strength, impact strength, and high continuous usage temperature, can exceed a certain degree. Long-term usage temperatures are over 100 C, allowing for a long operating period. It is appropriate for machinery, electronics, automotive, agricultural, or structural goods.

Question 2

What is the difference between engineering plastic and speciality plastic?

Accepted Answer

Engineering plastics are a class of plastic materials that have superior mechanical and/or thermal properties to commodity plastics. In many applications, manufacturing plastics have increasingly replaced conventional engineering materials such as wood or metal. Engineering plastics, in addition to equaling or exceeding them in weight/strength and other properties, are much simpler to produce, particularly in complex forms. Speciality plastics are those that follow more stringent specifications than regular or engineering plastics. They are more costly and are used in smaller quantities.

Question 3

What are the advantages of using engineering plastics?

Accepted Answer

- High service temperature
- Better solvent resistance
- Improved mechanical properties compared to commodity plastics
- Excellent electrical insulation properties

Question 4

What is titanium?

Accepted Answer

Titanium is a silver-colored metal with the symbol Ti and the atomic number 22. This is why certain brands use a lot of Ti2, or Ti22, in their products. Titanium has a very high strength-to-weight ratio, and can be up to four times stronger than steel but just half the weight, making it a very popular metal in the manufacture of aircraft and high-end sports cars.

Question 5

What are the benefits of titanium?

Accepted Answer

Titanium is a light metal with the highest strength-to-weight ratio of any metal. It means you can wear a chunky 8mm diameter wedding ring without getting weighed down. Titanium rings are totally hypoallergenic, making them an excellent substitute for a wedding ring for those with a metal allergy.

Question 6

How do you differentiate between glass and glass fibre?

Accepted Answer

Glass fiber is a material made up of numerous extremely fine glass fibers. As compared to glass, glass fiber has high tensile strength. The composition varies slightly, but not significantly, depending on the application, and includes a greater quantity of silica. Sizing (chemical application) is performed during the glass-to-glass fiber conversion process.

Question 7

How do you handle glass fiber?

Accepted Answer

Glass fiber insulation can be handled with gloves and a dust mask. Glass fiber cloth can be handled with bare hands unless you are cutting it and making small shards that will get in your skin. Then gloves and a dust mask. Glass optical fiber is remarkably strong. - Caution, a broken fragment that gets in your eye cannot be seen by the eye doctor to remove it.
