Polyonics has launched a new class of heat resistant tapes that safeguard heat sensitive devices in harsh conditions. As electrical and electronic devices evolve, their sizes are shrinking with increasing number of components accommodated very closely to one another to conserve space. This increases the sensitivity of the devices to heat.
Dimension Stability of the Polyonic Tapes
In order to handle the enormous heat generated and to safeguard the devices and enhance their functionality, it is essential to develop advanced materials that can perform these functions. The thermal resistant tape from Polyonics is one such material.
The new product is offered in two variants, namely, single and double coated thermal resistant tapes. The tapes are ideal for high temperature masking and bonding applications in electronics as well as in communication, medical, automotive and aerospace industries. While the single coated tapes are deemed as alternatives for conformal coatings employed in electronics manufacturing, the double coated tapes are considered as alternatives for conventional fasteners, adhesives and welds in the HVAC industry.
The key aspect that determines the heat management capability of the tapes is the dimensional stability. It is the ability of the tape to retain its shape under heat. If the dimensions of the tape change on exposure to heat, thermally sensitive portions of the devices will be vulnerable to damage. The Polyonics tapes are made from polymide and polyester which possess low coefficient of thermal expansion, high strength and chemical resistance.
Another key aspect that determines the tape performance is the design of the adhesive, PSA. The PSAs are made of silicone or acrylic and are integrated with nanoparticles and dimension control additives by employing the ThermoGard technology to manufacture them. The Polyonics tapes can also be engineered to incorporate static dissipative properties and halogen free flame retardant capability to prevent fire.
