Conjunto de compresión o resistencia a la compresión

Conjunto de compresión o resistencia a la compresión / Compression set or compression resistance

Para productos de espuma en la fabricación de calzado, nos gusta saber cuánto durará la espuma si la construimos en una plantilla o entresuela. El conjunto de compresión es la cantidad de espuma que se recuperará después de ser comprimida. El conjunto de compresión se mide en

un porcentaje. Una espuma que se resiste a la compresión podría tener un puntaje de 4%, una espuma que está muy dañada por el impacto puede tener un puntaje de 45%. EVA de mala calidad tendrá un alto valor de compresión establecido. La espuma de PU de alta calidad durará para siempre con un conjunto de compresión muy bajo.
