About us
Calandex Innovation and Technology (HK) Company Limited
With the brand Premium Living Concept is new in Hong Kong. Our technology is one the most advanced technology in the world and under our own patents. We are emphasis on using Graphene (nanotube Carbon) technology and its new usage in changing our daily living, all related to warming or heating tools/utensils/machines.
In 2019 we use our polymer under several thousand times testing and
develop PTC which a branded new in the market. By using Carbon
nanotube application, our Graphene nature technology can create
many new concepts electrical appliances which is under safety scope
low voltage and much in energy saving level.
In 2022, our technology has great breakthrough and has an advanced
level. Our Graphene heating film can appear in different forms. The
thickness can be thinner than 0.1mm and the texture can be in hard film
or in soft plastic like (actually iit is not only plastic, it is a specific PC) In
addition, the film temperature can be varied from several 10ºC to several
hundred degrees, depends on the request of the clients (products).
We have the mission for saving the world energy and in a much
safety life!!
