Characteristics and uses of nine plastic materials commonly used in industrial design

Share your common sense of industrial design materials. Plastics are most commonly used materials in industrial design. Here are nine plastics, their characteristics, uses and differences. I think you will have a clear idea about them.

PET (polyethylene terephthalate)

Characteristics and uses of nine plastic materials commonly used in industrial design

The most common plastic products in hot summer are drinks that quench your thirst, and plastic bottles for these drinks are PET.

PET, Chinese name: polyethylene terephthalate, which is often used to make mineral water bottles, cola drink bottles, juice bottles; film for mobile phones or tablets; "true goodness" of last century also comes from PET. .

Tips: Do not pour hot water into coca-cola bottles and beverage bottles, because due to properties of material, PET releases toxins when exposed to high temperatures above 70 °C; do not keep alcohol or vegetable oil; do not put drinks in sun In a car in sun, drink bottles release toxins after 10 months of use, so it is not recommended to reuse these bottles for food.

HDPE (high density polyethylene)

With regard to HDPE, most common ones are plastic grocery bags, shopping bags, detergent bottles, and edible yogurt bottles.

Advice. Although this material can be recycled, its surface is difficult to clean and bacteria can easily grow on it, so it is not recommended for use in food and medicine.

PVC (polyvinyl chloride)

PVC is also a common plastic in our daily lives. For example, raincoats are made from this material. There are also sockets, water pipes, etc.

Tips: This material is not suitable for food, please do not contact with food.

LDPE (Low Density Polyethylene)

The Chinese name for LDPE is low-density polyethylene, which is often used in production of plastic film and toothpaste.

Advice. The plastic film melts at 110°C and must be removed before heating in microwave.

PP (polypropylene)

PP has a wide range of applications in plastics industry, and its food-safe properties and transparent texture are best choice for making fresh food storage boxes, lunch boxes, plastic water cups and baby bottles.

Tips: PP material has good heat resistance, for example, LocknLock fruit and vegetable container can withstand high temperature up to 110°C, but some fruit and vegetable container lids are not made of PP, so you should check material label clearly if not polypropylene to be removed. cover when heated.

PS (polystyrene)

Polystyrene, abbreviated as PS in English, is often used to make cheap fast food boxes, foam packaging materials, ice packs, etc.

Tips: PS releases toxins when in contact with strong acids and alkalis, so avoid contact with them. In addition, disposable polystyrene packaging box is not allowed to pack hot items, and it cannot be used for heating in a microwave oven.

PC (polycarbonate)

Our widely used transparent water glasses, drinking buckets and other products are made of polycarbonate.

Advice. If you choose a plastic water cup, be sure to check if it contains BPA. Only this confirms that it is a safe food grade plastic.

PA (polyamide)

Polyamide is also called nylon, and nylon ropes, fishing nets, conveyor belts, etc. are made from PA (polyamide). Under nylon products, there are many subsections that are widely used, mainly for engineering plastics.

Advice. Nylon socks and fabrics are poorly ventilated and prone to static electricity.

ABS (polyamide)

ABS is a terpolymer of acrylonitrile, butadiene and styrene. By adjusting proportion of formula, it can have excellent mechanical properties of toughness, hardness and hard phase balance. Therefore, it is widely used, for example, in most of our household appliances, mice, toys, etc.

Advice. The ductility of finished ABS plastic products is a little low, so household appliances should be stored in places where there is too much sunlight to prevent accelerated aging of plastic.
