Soft Plastic Rapid Prototype
Low hardness plastic is called soft plastic. The hardness ranges from 30-90. It is relatively soft at room temperature. Soft plastic has excellent elasticity, slip resistance, and vibration damping performance. It is necessary during the development of most products. The common soft plastic includes TPE、SBS、TPU、TPV、rubber（SBR）and silica gel, and they are widely used during the process of soft plastic rapid prototype. TPR is softer than rubber, but in terms of tensile strength, fatigue resistance and mechanical performance, it is inferior to perduren.
Soft plastic rapid prototype uses vacuum duplex mold to fabricate. It is deformed, stirred, preheated, and injected in vacuum, and re-solidified in thermotank at the temperature of 60-80℃ for 2-3 hours. It is suitable for the small-batched pilot prototype with complex structure, regular thickness, and functions. The common applications include keyboard of remote, watchband and baby pacifier.
Choosing the right prototype provider is the first step of success during new product development. When choosing the soft plastic rapid prototype provider, the quality should be taken into consideration as the first indicator, other than the cost. Bordersun has been focused on soft plastic for 18 years. With the exquisite technique and efficient service of over 20-year experienced technicians, Bordersun received the recognition of customers worldwide, expanding our business to east Asia, Europe, North America, South America and South-east Asia.
The soft plastic rapid prototype made by Bordersun got certified by RoHS and REACH. The difference between RoHS and REACH is that: RoHS forbids the use of particular chemical in electro and electric devices; while REACH has limitation on nearly all chemicals, including the chemical, material, solvent and paint used in products.
