How do ODM manufacturers test the resistance of outdoor furniture to sap stains?

ODM manufacturers rigorously test outdoor furniture for resistance to sap stains to ensure durability and longevity. The process typically involves controlled exposure to tree sap, followed by evaluations of material reactions. Common methods include applying synthetic or natural sap to furniture surfaces under varying environmental conditions, such as sunlight and humidity. Manufacturers assess staining, discoloration, and ease of cleaning. Advanced testing may involve accelerated weathering machines to simulate long-term exposure. High-quality outdoor furniture undergoes multiple cycles to guarantee performance, ensuring it withstands real-world conditions while maintaining aesthetic appeal. These tests help ODM manufacturers deliver products that meet industry standards and customer expectations.
