Epe Foam Pipe Machine

Polyurethane foam on the market a wide range of various brands, various shapes, a variety of names of the number of EPE Foam Machines are numerous, and the new brand, the new name of the EPE Foam Machine is also constantly introduced. Many models, so that manufacturers dazzled, so that the wrong model, in order to facilitate the producers choose the right foaming machine, now talk about the choice of EPE Foam Machine.

Fully understand the type of EPE Foam Machine
Although the basic principle of the foaming machine is to introduce blowing gas into the aqueous blowing agent, different types of foaming machines introduce different gases in different ways. Know the type of EPE Foam Machine to know its way of airing, which to further understand its technical characteristics and the use of a great help, help producers to grasp the overall.

For example, low-speed mixing type is driven by slow rotation blade gas, bubble production is small, foaming efficiency is low; high-speed impeller type is driven by high-speed rotating impeller, bubble diameter can not control the bubble uneven; high pressure and low pressure type production Bubble speed, high efficiency, uniform bubble, small.

Clear the advantages and disadvantages of various types of polyurethane EPE Foam Machine, and then select the EPE Foam Machine is easy. Therefore, a full understanding of the type of EPE Foam Machine, the producers choose the right EPE Foam Machine plays a vital role.

Carefully grasp the basic technical parameters of the EPE Foam Machine
For the producers, just understand the model and the principle of foam is not enough, but also need to further understand the foam several important technical parameters to determine whether to meet their own production requirements.

● Production: Yield is the amount of production, the amount must be slightly higher than their own need to bubble 20%, to leave room for its production should be the lower limit of the calculation of the basis for the calculation, but not the upper limit;

● Installed capacity: Installed capacity is the total installed power, this parameter on the calculation of electrical appliances to the total power of the adaptability of the important significance;

● Equipment size: This parameter is the necessary layout of the workshop layout of the necessary factors;

● Bubble diameter range: The general should be based on the specific product requirements of the bubble to control.

Carefully understand the quality of foam
Polyurethane EPE Foam Machine is the ultimate product of the bubble, and the production process we need is the bubble, so the quality of the bubble is good or bad to determine the performance of the unique standards of foam. Determine the foaming quality of the foaming machine, which should be mainly in three aspects, namely, foam tightness, foam uniformity and foam bleeding.

Foam fine refers to the size of the bubble diameter, the smaller the bubble diameter, the more dense foam dense, the better the stability of the foam, the higher the strength of the product produced, the better the insulation performance.

Bubble uniformity refers to the size of the bubble should be uniform, the bubble diameter the more uniform the narrower the distribution, the more stress the product, the better the use of the effect.

Bubble bleeding refers to the amount of foam produced after the bubble burst, the lower the amount of foam bleeding, the lower the water content of the foam, indicating that the foaming machine foam better.

Foaming machine in the above three areas can meet the requirements, should be confirmed by the test machine approved. In the choice of EPE Foam Machine, the foaming machine must be issued by the bubble must be more water and less sponge-like small foam, and even fine.

The similar types of closed cell foam, expanded polyethylene (EPE) and ethylene-vinyl acetate (EVA) foams, constitute the biggest portion of the market in their product sector. Both exhibit excellent salient features, such as shock absorption, flexibility, thermal insulation, and water resistance. Both can also be produced at reasonable prices and often overlap in terms of function. Nevertheless, a side-by-side comparison of these foams' inherent physical properties reveals a number of crucial differences.

Resilience
EVA foam can be more resilient than EPE, with the former's tensile strength exceeding that of the latter by as much as several orders of magnitude. Compressive strength and elongation follow suit. EVA foam's greater recovery characteristics make it an excellent and cost-effective substitute for rubber in some applications, such as shoe soles and trampoline pads. In spite of EPE's comparatively low elasticity, however, it remains flexible enough for wrapping about shock-sensitive products, making it an efficient packaging material.

Thermal Properties
EPE foam has better thermal properties than EVA. Typical values for thermal conductivity range from 0.01–0.02 BTU/hr-ft°F for EPE foam, and 0.25–0.29 BTU/hr-ft°F for EVA. EPE's low thermal conductivity gives it excellent heat resistance, making it a good insulating material for walls, ceilings and roofs. Its effective service temperature ranges from -58°-158°F. For temperatures exceeding this, EVA foam becomes a better alternative up to around 176°F.

Durability
One of EVA foam's biggest advantages over EPE is its durability. Average EVA foam density and tear strength values stand at five or more times that of an ordinary EPE foam. Because of their closed-cell structure, both have exceptional cushioning and shock proofing capabilities, but EVA foams last much longer. This naturally translates to a higher price, which makes EPE a better choice in cases where cost takes precedence over product lifetime.

Uses and Applications
Both materials show superb versatility, with applications ranging from sports equipment and packaging to soundproofing and insulation. EPE foam remains the choice material for applications that put a premium on cost-effectiveness over durability. Examples of these include packaging, carpet underlays, luggage lining, car door panels and car seats. EVA, on the other hand, takes the lead in applications where sturdiness is of utmost importance.
