Read： 579 Time：20months ago Source：Transform the World with Simplicity

Thermoplastic polyurethane elastomer rubber (TPU) is a high-performance chemical raw material with excellent physical properties and a wide range of applications. In order to ensure the safety and reliability of the TPU during storage and transportation, a series of strict specifications need to be followed. This article details the safe storage and transport specifications for TPUs.

1. storage specification

1. Storage environment: TPU should be stored in a dry, ventilated and clean indoor environment, avoiding direct sunlight and high temperature. The recommended storage temperature is -10 ℃ ~ 30 ℃, and the relative humidity is between 50% ~ 70%.
2. Storage container: TPU should be stored in a special sealed container or packaging bag to prevent the intrusion of dust, moisture and other impurities. The container should have good sealing performance and oxidation resistance.
3. Storage period: TPU has good long-term storage stability, but aging and yellowing may still occur during storage. Therefore, it is recommended that the storage period is 12 months, after which the quality inspection should be carried out again.

2. transport specifications

1. packaging requirements: TPU should be used in the transport process of special bags or containers for packaging, to ensure that the product will not be damaged due to friction, collision and other reasons. At the same time, the packaging should be marked with product name, quantity, production date and other information.
2. Mode of transportation: TPU can be transported by cars, trains, ships, airplanes and other modes of transportation, but the appropriate mode of transportation should be selected according to the quantity and distance of the product to ensure the safety and timeliness of the product during transportation.
3. Matters needing attention during transportation: During transportation, the product should be prevented from being affected by direct sunlight, high temperature, rain, etc. to ensure product quality. At the same time, attention should be paid to prevent the product from being squeezed, collided and other external forces to avoid product deformation or damage.

3. safety specifications

1. Personnel safety: In the process of storing and transporting TPU, ensure that the operators have relevant safety knowledge and skills, abide by the safety operation procedures, and wear necessary protective equipment to prevent injury to personnel.
2. Fire and explosion-proof: TPU has a certain degree of flammability, so attention should be paid to fire and explosion-proof during storage and transportation. The storage and transportation places shall be equipped with corresponding fire-fighting equipment and facilities, and regular safety inspections and drills shall be carried out to ensure the effectiveness and reliability of safety measures.
3. Environmental protection: In the process of storing and transporting TPU, attention should be paid to the protection of the environment to avoid pollution to the environment. Waste TPU products and packaging materials should be properly treated and recycled to reduce environmental impact.

In short, thermoplastic polyurethane elastomer rubber has important application value in the field of chemical production raw materials, but it needs to comply with strict safety regulations during storage and transportation to ensure product quality and safety. By complying with the above specifications, the safety and reliability of TPU during storage and transportation can be effectively guaranteed, and a stable and high-quality raw material supply can be provided for chemical production.
