Introduction

Agricultural insulation facilities play a crucial role in modern agricultural production. Whether it is a greenhouse, livestock and poultry house or aquaculture pond, the performance of insulation facilities directly affects the growth of crops, the health of animals, and the benefits of breeding. As a highly efficient insulation material, polyurethane foam is widely used in agricultural insulation facilities due to its excellent thermal insulation performance and construction convenience.
