The commonly used vacuum forming materials include PVC (about 50%, density 1.36g/cm3), PS (about 30%, density 1.06g/cm3), PET (about 10%, density 1.39g/cm3), and PP (about 10%, density 0.92g/cm3).
The maximum thickness of PVC is generally 0.8mm, and PS can generally reach 1.2mm. Films exceeding this thickness are difficult to pull and can easily cause equipment damage.
The color of materials is generally determined based on customer requirements, such as PANTON color codes, color drafts, color separation standards, etc., or rough colors can be specified by the customer and provided to the customer based on product inventory.
If the customer has no requirements, colorless, transparent, and easiest to produce materials can generally be used. If you order colored sheet materials, it usually needs to be at least 2 tons to be customized.
Colored materials have a higher density than transparent materials. Flocking materials generally use PS materials with lower density. If the density is high, it is easy to produce a lack of fuzz on some surfaces after stretching.
Generally, materials with bright colors are easier to produce and do not have high packaging requirements. Scratches on light colored materials are easily noticeable, and strict packaging requirements are required. Generally, flocking materials need to be protected from scratches and indentations.
When products are placed together, they are prone to friction and whitening in tight contact areas. For places like this, special attention should be paid when packaging.
If strict requirements are required, methods such as using plastic bags or separating copy paper should be considered for protection. Flocking materials are generally ordered based on length (meters).
The characteristics of materials generally include anti-static properties. Anti static materials are made by soaking or adding anti-static components, and the latter method has long-lasting anti-static performance.
The static electricity value of anti-static materials can generally reach 106-1012 Ω. In addition, there is environmental friendliness, with APET being the most environmentally friendly and PVC being recyclable.
Generally speaking, the thicker the material, the longer the heating time required, and the slower the production speed; The thinner the material, the faster the production speed, but the length of a roll is also longer.
