Understand plastic's low-temperature characteristics
Understanding the low-temperature characteristics of plastics is crucial to preventing cracking. Different types of plastics exhibit varying behaviours at low temperatures, with some becoming brittle and susceptible to impact damage, while others maintain their flexibility.
Polyethylene and polypropylene, for instance, possess good low-temperature resistance and can be used at lower temperatures without the risk of cracking. On the other hand, plastics such as polyvinyl chloride and polycarbonate have poor low-temperature resistance and must be used at higher temperatures to avoid potential cracking.
The service temperature of plastic materials significantly impacts their performance and longevity. Therefore, it is essential to control the use temperature to prevent cracking. Plastics should be stored in a relatively high-temperature environment during winter, and insulation measures should be implemented to protect them from extremely low temperatures.
Additionally, it is important to consider the mechanical values of plastics at the upper end of their service temperature, rather than at room temperature. This is crucial for selecting the most suitable material for specific applications.
Transportation and construction processes can also introduce stresses that increase the likelihood of cracking. During these stages, plastic materials should be handled with care to prevent impact, excessive stress, or damage.

Handle with care during transportation
Plastic is a versatile material, but it is susceptible to cracking, especially during transportation. Here are some detailed instructions to prevent plastic products from cracking during transportation:
Firstly, understand the characteristics of the plastic product. Different types of plastics have varying properties, including resistance to low temperatures. Some plastics become brittle in cold conditions and are more prone to cracking when exposed to impact. Therefore, it is essential to know the specific plastic's low-temperature characteristics to take appropriate precautions during transportation.
Secondly, control the temperature during transportation. As mentioned, low temperatures can make plastic brittle, increasing the likelihood of cracking. To mitigate this, ensure the plastic product is transported in a temperature-controlled environment, maintaining a relatively high temperature to prevent the material from becoming brittle.
Thirdly, handle the plastic product with extreme care. Avoid any actions that may cause impact or excessive stress on the plastic during transportation. This includes not throwing, dropping, rolling, or dragging the product. Open flame bending of pipes should also be strictly prohibited. By reducing the impact and stress on the plastic, the chances of cracking are significantly reduced.
Additionally, consider the use of protective packaging or cushioning. To further minimise the risk of impact and stress, package the plastic product securely, using suitable cushioning materials such as bubble wrap or foam. This protective layer will help absorb any shocks or vibrations during transportation, reducing the chances of the plastic coming under stress and potentially cracking.
Finally, avoid the use of certain chemicals. Chemical exposure can trigger and accelerate the stress-cracking process in plastics. Avoid using harsh chemicals, such as acetone, during transportation, and be mindful of any chemical-based adhesives that may come into contact with the plastic. Always refer to the plastic's specifications to determine its compatibility with chemicals.
