• It is highly resistant to wear and tear, making it ideal for use in products like ropes, fishing nets, and parachutes.

• Nylon is also known for its low moisture absorption, which allows it to maintain its properties even in humid conditions.

• It has good chemical resistance and can ...read more

Different materials have different melting temperatures.

• Melting temperature is the temperature at which a solid turns into a liquid.

• Metals generally have high melting points, while plastics have low melting points.

• For example, the melting point of iron is around 1535°C, while the melting point of polyethylene is around 115°C.

There are various types of grades depending on the context.

• Grades can refer to academic performance, job positions, or quality of products.

• In academics, grades can be A, B, C, D, or F.

• In job positions, there can be different grades such as junior, senior, or executive.

• In quality control, grades can be assigned based on the level of defects found in a product.

• The number of types of grades can vary depending on the context.
