Teach You Three Strokes Of Slow Rebound Memory Pillow

- Sep 01, 2017 -

A look whether pure material. Is the pillow made of 100% polyurethane, add talcum powder to increase high-density? This is the industry's production process and high-density secret. At present, the slow rebound pillow in the Chinese market more than 90% of the non-pure material production, so the density index is gradually difficult to measure the true quality of pillows.
See if you've passed security? Slow rebound material, belonging to chemical substances, from the chemical composition has a certain harm, so the production must control his safety indicators, slow rebound poisonous harmful substances are fully played, to see if a pillow is appropriate, to see if his safety test indicators passed? At present, the slow rebound product testing including toxic and harmful substances detection and pure material testing.
Three see density: density is high-grade slow rebound material of one of the basic indicators, general molding process polyurethane density can be done 70~150d, cutting process can do 40~100d, due to technical bottlenecks and equipment differences, the domestic production of polyurethane density is generally lower than 100D, And the highest foreign can reach 150D, and then even the same density of products will be very different, mainly the formula, technology and raw materials caused by the difference, that is, high-grade slow rebound material must be high-density, but only high density is not necessarily high-grade material. The density is above 150 kilograms per cubic metre. Normal memory sponge density is usually only about 40-50 kg/m³.
