Si-TPV silicone-based thermoplastic elastomers, helping to re-upgrade the design of Vacuum cup!

describe:

The weather is gradually turning cooler, the insulation cup is a must-have item in the fall and winter for every hit worker.

Vacuum cup is generally made of ceramic or stainless steel plus a vacuum layer made of water containers, the top has a lid, sealed tightly, the vacuum adiabatic layer can be mounted on the inside of the water and other liquids to slow down the dissipation of heat, in order to achieve the purpose of heat preservation. Thermos from the development of the thermos flask, the principle of heat preservation and thermos flasks, just people for the convenience of the bottle into a cup.

Detail

A good insulation cup not only can effectively maintain the temperature of the beverage, but also provide excellent sealing performance. Of course, it is even more critical that the sealing part of the insulation cup is made of contact-safe materials.
A good thermos not only needs to be versatile, but it also needs to meet the relevant food contact grade safety regulations.

Application

Not only can it be applied in the field of thermal insulation cups, but it is also widely used in many fields of food contact, such as cup seals, lunch box seals, etc., which significantly improves the product performance and use experience. In the future, Si-TPV silicone-based thermoplastic elastomers will gradually penetrate into all aspects of our daily life and work, creating a more comfortable and safer life for us. Si-TPV silicone-based thermoplastic elastomers will also continue to innovate themselves in order to create a better life, and build a more complete and richer product system.

SILIKE has developed a new plasticizer-free elastomeric material（Eco-friendly soft touch material） – Si-TPV silicone-based thermoplastic elastomers – for this application. This series of Elastomeric Materials have been tested by the US FDA and China’s food safety monitoring agency for food contact grade safety, ensuring that the products are free of BPA, heavy metals, plasticizers and other harmful substances to the human body.

Compared with TPR materials, Si-TPV silicone-based thermoplastic elastomer materials are good overmolding materials with excellent soft-touch overmolding effect and processing fluidity.Compression permanent deformation is small, with excellent resilience, excellent sealing effect, as well as good abrasion resistance, can effectively prevent heat loss, to ensure that the beverage temperature is maintained for a long time, to extend the service life of the insulation cup, and at the same time will not produce harmful substances, to protect the health of the insulation cup seals, very suitable for insulation cup sealing applications.

Si-TPV silicone-based thermoplastic elastomers have excellent coloring ability and can be dyed into a variety of colors according to different needs. The color flexibility and high color saturation provide designers of insulation cups with greater freedom of innovative design. In addition, Si-TPV silicone-based thermoplastic elastomers are self-developed, Environmentally Friendly Thermoplastic Elastomers that use solvent-free technology, contain no plasticizers or softening oils, and are DMF-free, 100% non-toxic, odorless, and meet FDA food-grade requirements, as well as being low-carbon and recyclable, making them friendlier to the human body and the environment, and promoting the recycling of the green economy, which makes them an ideal choice for manufacturers aiming to reduce their carbon footprint. choice.
3. Thermal Stability Across a Wide Operating Range: TPEs have a broad operating temperature range, from low temperatures near the elastomer phase’s glass transition point to high temperatures approaching the thermoplastic phase’s melting point. However, maintaining stability and performance at both extremes of this range can be difficult.
Solution: Incorporating heat stabilizers, UV stabilizers, or anti-aging additives into TPE formulations can help extend the material’s operational life in harsh environments. For high-temperature applications, reinforcing agents like nanofillers or fiber reinforcements can be used to maintain the structural integrity of the TPE at elevated temperatures. Conversely, for low-temperature performance, the elastomer phase can be optimized to ensure flexibility and prevent brittleness at freezing temperatures.
4. Overcoming the Limitations of Styrene Block Copolymers: Styrene block copolymers (SBCs) are commonly used in TPE formulations for their softness and ease of processing. However, their softness can come at the expense of mechanical strength, making them less suitable for demanding applications.
Solution: A viable solution is to blend SBCs with other polymers that enhance their mechanical strength without significantly increasing hardness. Another approach is to utilize vulcanization techniques to toughen the elastomer phase while preserving a soft touch. In doing so, the TPE can retain its desirable softness while also offering improved mechanical properties, making it more versatile across a range of applications.
