What are the common bubbles?
There are many kinds of common foams, such as EVA foam, EPE foam, also known as pearl foam, sponge, CR foam, aluminum foil foam and so on.
1, EVA foaming: resin is characterized by good flexibility and rubber-like elasticity. The foam can still maintain good flexibility, good transparency and surface gloss, good chemical stability, good aging resistance and ozone resistance at -50℃, and is non-toxic. Good miscibility with filler, good coloring and molding processability.
2.EPE, also known as pearl cotton: polyethylene foam is a non-crosslinked closed-cell structure and a new type of environmental protection foam packaging material. It has many advantages such as waterproof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and so on, and also has good chemical resistance.
3. Sponge: It is a porous foam material with good water absorption and can be used for cleaning articles. Mixing foaming resin, foaming assistant and adhesive resin (making the finished product sticky); Sponges mainly include: industrial sponges: foamed cotton, shaped cotton, rubber cotton, memory cotton and so on.
4. Aluminum foil foam: Use flexible pure aluminum foil and glass fiber instead of conductive cloth to wrap the flame retardant foam. Surface impedance? 0.0 16? , has excellent metal shielding performance, its temperature resistance can reach 130℃, and its lower cost can meet the demand of product cost pressure.
5.CR foam: it is a kind of general special rubber, which has good physical properties of general rubber, flame retardant, oil resistance, chemical corrosion resistance and other excellent characteristics, so it plays an important role in various synthetic rubbers.
How to process special-shaped foam
At this time, we will use our common foam cutting machine. Using precision foam cutting machine instead of expensive laser cutting machine is beneficial to high-speed precision cutting of medium and thin plates with large consumption. The specially reinforced bed structure makes the water cutting bit not vibrate when it runs at high speed, and the whole machine runs bumpy and the cutting speed is fast. And the machining accuracy is high. Omni-directional cutting ability, can stop any three-dimensional curve cutting.
What are the common types of bubbles? How to process special-shaped foam? You know what to do when you have the answer. When processing foam, you must find a regular processing factory, so that the specifications processed can satisfy you or be customized for your own use. There are many different types of bubbles and different advantages.
