Comparison of PPO material and PC material in solar photovoltaic connector

There are significant differences in the characteristics between PPO and PC materials. PPO material (polyphenyl ether) is one of the five general engineering plastics in the world, which has the characteristics of large rigidity, high heat resistance, flame retardant.At the same time, it also has the characteristics of wear resistance, non-toxic, pollution resistance and so on. In contrast, PC material (polycarbonate) has low hardness, but good toughness, high transparency, but poor chemical resistance, easy to be corroded by acid and alkali. ‌ ‌

The difference between PPO material and PC material mainly lies in the performance, use and price.

1、Performance

（1）resistance to elevated temperatures

PPO：With a high glass transition temperature (about 220°C), it can maintain stable physical and mechanical properties in high temperature environments.

PC：It has a high thermal deformation temperature (usually more than 125°C) and can maintain good stability under high temperature conditions.

other material：Common plastics such as polypropylene (PP) and polyethylene (PE), for example, are less resistant to high temperatures and usually start to soften or lose stability at lower temperatures.

（2）mechanical strength

PPO：With high mechanical strength and rigidity, it can resist mechanical stress, vibration and impact.

PC：It has good strength and rigidity, and is harder and more brittle than PPO, but it is also more susceptible to ultraviolet aging.

other material：Mechanical strength and rigidity vary depending on the specific type of plastic, but in general, other common plastics have lower mechanical strength compared to PPO and PC.

（3）chemical resistance

PPO：It has good corrosion resistance to acid and alkali solution, grease and some chemical substances.

PC：It has good corrosion resistance to acid and alkali solutions and some chemical substances.

other material：Different plastics have different chemical corrosion resistance properties, and some may be more sensitive to the corrosion of acid and alkali solutions and chemicals.

（4）insulating property

PPO：With good insulation performance, it can effectively isolate electrical components and prevent current leakage and short circuit and other problems.

PC：It has better insulation performance, but its insulation performance may be slightly lower than that of PPO.

other material：Different plastics have different insulating properties, and some common plastics such as polyethylene (PE) and polypropylene (PP) have relatively poor insulating properties.

2、Use

PPO：It is mainly used in electrical and electronic fields, such as tuning blades, coil cores, microwave insulation components, shielding sleeves, high-frequency printed circuit boards, etc. In addition, it is also used in the automotive industry, mechanical industry and chemical fields.

PC：It is widely used in electronic equipment, automobile industry, industrial components and various industrial equipment casings.

3、Price

PPO：The price is relatively high.

PC：The price is relatively low.
