Dongguan factory specializing in the production of automotive supplies high-density foam sponge

Dongguan City Yu Rong Plastics Co., Ltd. is engaged in: furniture foam, memory foam, specialty packaging sponge, EVA sponge, absorbing sponge. Production, research and development, design, sales of sponge products manufacturers. Products in addition to the production of the conventional density foam, the same time the production of various types of functions and requirements of different sponges. British standard fire sponges such as requiring Stuttgart hard sponge, special soft sponge, sponge strong rally, as well as special features, American standard fire sponges, antistatic sponges, slowly rebound sponges. Customers can also request the production of high-density foam sponge for each color (High-density foam) is the weight per cubic meter 45 kg of sponge sponge. Now sponge process has been improved, simple weight to determine the density of the sponge no longer desirable. Now the process of sponge, density, weight, much lighter than the previous process of sponge. High density foam is not simply to determine the density of the weight. Rationale editor in physics, to a certain quality material per unit volume is called density of the material. Symbol ρ (read rōu). International Master in kg / m3 ;, common unit also g / cm3 ;. The mathematical expression is ρ = m / V. In the International System of Units, the quality of the main unit is kg, the main unit volume is cubic meter, then take the quality of one cubic meter as the density of the material substance. For non-homogeneous materials are called "average density." Index density foam density is an important indicator species, high density foam, which illustrate the gap is small, the greater quality. For example: 40 is the weight of one cubic meter density foam is 40 kg, 50 density is 50KG per cubic meter. Sponge process has been improved, not mind the weight to determine the density. But in a more professional technical standards to determine the density of the foam pad. 2 classification editor sponge in the industry to distinguish the method is based on density division, sponge density is KG / M3. Is the weight per cubic meter sponge. Common sponge is structured into high-density foam, foam density, low density sponge three. High-density foam, Hole, very full, often used for sound-absorbing cotton, sofa cushions, bags and other soft materials. According to the national customs authorities to explain ≥45 density is high density, density of between 45 to 18 density, density <18 low density. 3 use editing high-density foam hardness generally high-density foam hardness is also high, but do not rule out some high-density super soft foam additives are added, so that the sponge becomes ultra soft, sound-absorbing cotton used to make sofa cushion soft packing material. Medium density, low density foam used for general protective material. The hardness of the foam of the same density is not the same. Usually do sofa cushion sponge density of about 35, there are soft, hard, super soft, and other specifications. Do mattress is generally about 22. The so-called high-density foam is a salesman of goods commonly used terms. High density foam is generally not used absorbent. The use of high-density foam to absorb external forces have, feel fine, soft, comfort features, in car, furniture, health care, toys and other industries, can meet a variety of market demand density of the sponge is usually: 10-50KG sponge thickness: can production of various thickness of the sponge according to customer requirements colors: black, white, color quality management system: ISO9001 authentication. Fire sponge: produce British standard, American standard, Canada and other standards.
