Hello, We are a refrigerant company. We make and sell hydrocarbons. This time we are going to supply hydrocarbon refrigerant to a car maker. But as you know, still now most car makers are using Freon and HFCs. As you know, in Australia, Canada and some other countries. hydrocarbons are used in mobile air conditioner(MAC). By making sure that already there are car makers using hydrocarbons in the process & car production. We'd like to persuade one car maker to use hydrocarbon refrigerant instead & HFCs. So it will be very appreciated if you could give us information on the country and car maker which use hydrocarbons in the process & car production. We are looking forward to hearings from you soon. Thank you for your help in advance. 매끄럽지 못한부분 수정좀 부탁해열 ㅠ_ㅠ
