Innovative and more sustainable PU applications in the cold chain industry
PU helps preserve food
Many foods transported at room temperature are prone to spoilage, so cold chain transportation is often used to ensure food safety. Efficient cold chain transportation keeps perishable food well preserved, and PU is an essential element throughout the cold chain journey. The PU sandwiched between the insulation layers of various parts of refrigeration and freezing equipment can keep out the ambient temperature and ensures the freshness and safety of food.
PU helps save energy and reduces emissions
PU helps protect the environment
According to national regulations, starting from January 1, 2019, no enterprise may use HCFC-141B as a foaming agent to manufacture refrigerated containers. Covestro is the first PU manufacturer to develop a more environmentally friendly cyclopentane foaming agent to replace 141B foaming agent in the refrigerated container industry. In 2015, it successfully helped the three largest refrigerated container manufacturers in the industry - Maersk, CIMC, and Singamas - to replace 100% of the 141B system, thus jointly creating a more environmentally friendly refrigerated container transportation industry.
Excellent performance of PU foaming systems
- Food preservation PU can be used in the insulation layer of various parts of refrigeration and freezing equipment such as cold storage, refrigerated trucks and containers, and refrigerated display cabinets and commercial household refrigerators to protect from ambient temperatures and ensure the freshness and safety of food.
- Excellent formula performance Rigid polyurethane foaming systems based on different foaming agent or additive formulas have an excellent thermal insulation performance, physical properties, adhesion, high temperature resistance, durability and flame retardant properties.
- Energy conservation and emission reduction As an efficient thermal insulation material, PU has made valuable contributions to energy conservation and the reduction of carbon dioxide emissions.
- Environmental protection PU cold chain solutions contain a cyclopentane foaming agent that replaces the 141B foaming agent to create a more environmentally friendly refrigerated container transportation industry.
