The impact of environmental conditions on PBT resin

Environmental conditions are one of the important factors that affect the performance and stability of PBT resin during use. As an engineering plastic, PBT resin may undergo changes in physical properties, chemical properties, thermal properties, etc. under different environmental conditions, thus affecting its performance in practical applications.

Temperature effect
high temperature
In a high-temperature environment, PBT resin may soften, thermally deform, etc., resulting in product size changes, reduced strength, and even loss of original structural stability. Therefore, when using PBT resin products in high-temperature environments, you need to choose a high-temperature-resistant PBT resin type and take measures such as lowering the temperature and increasing ventilation.
low temperature
In low temperature environments, PBT resin may become brittle, reducing its impact strength and toughness, making the product prone to breakage. Therefore, when using PBT resin products in low-temperature environments, it is necessary to select a low-temperature-resistant PBT resin type and take measures such as heating and insulation.

Humidity effect
high humidity
PBT resin has a certain degree of water absorption. High humidity environments may cause PBT resin products to absorb water and swell, resulting in dimensional changes and a decrease in mechanical properties. Therefore, when using PBT resin products in high-humidity environments, it is necessary to take measures such as moisture-proof and waterproof, and choose moisture-resistant PBT resin materials.
low humidity
In a low-humidity environment, PBT resin products may become brittle, reducing their toughness and impact resistance, and prone to breakage. Therefore, when using PBT resin products in a low-humidity environment, measures such as moisturizing and humidification need to be taken to prevent them from being affected by drying.

Lighting effect
Long-term exposure to ultraviolet light will cause photoaging of PBT resin, leading to surface oxidation, color change, strength reduction and other problems, affecting the appearance and performance of the product. Therefore, when using PBT resin products outdoors, it is necessary to take anti-UV treatment or choose PBT resin materials that are resistant to light aging.

Chemical environmental impact
PBT resin has different corrosion resistance to different chemical media. Some chemical substances may cause dissolution and softening of PBT resin, resulting in a decrease in product performance. Therefore, when using PBT resin products in specific chemical environments, it is necessary to select a PBT resin type that is resistant to chemical corrosion and take protective measures.
