특징

   선진각국의 세계 기후변화 협약에 의거하여 오존층보호와 지구온난화 방지의 추진 일환으로, 종전에 사용하던 CFC 계통 각종
발포제와 냉매를 공해가 없는 천연물질로 대체 사용이 의무화 되었습니다.
금번, 폐사에서는 종전의 경질 우레탄 발포제로 사용하던 프레온계 R-11 및 R-141b의 환경 보호 대체 발포제인 하기 천연발포제를 수입하여 귀사 제품의 환경문제와 원가 절감에 기여할 수 있도록 경쟁력 있는 가격으로 공급하여 드리고자 합니다.
   또한,  폐사는 천연발포제 Cyclopentane,   Iso-pentane,  N-pentane 공급 시스템 및 방폭설비 공사도 가능하오니 필요시 문의
바랍니다.

1) Cyclopentane(싸이클로펜탄) : R-141b의 대체 발포가스로, MDI 및 Polyol 혼합사용하여 대표적인 경질우레탄폼 생성함.
   (용도 : 냉장고단열재, 각종 고강도 보온재, 보온/보냉판넬)
2) LG전자, 삼정전자, 대우전자 및 중국, 인도, 태국, 중동 등 기타 해외 수출 거래처 다수
3) 포장 : 200 liters 드럼, Bulk Tank, ISO Tank container

주요고객 : ELECTROLUX, BOSCH-SIEMENS, HAIER, NATIONAL, SHARP, KELON, XINFEI, MEILING, HARTMANN(OEM)
Cyclopentane
  1. Molecular formula: C5H10
  2. Cyclopentane can be used as a new foaming agent for rigid polyurethane foam and can be substituted for CFCS which distroies the atmospheric ozone layer. Now it is widely used in producing non-CFCs refrigerator, freezer and cold storage and tubing insulating materials. With the coming of the deadline to use ODS by Montreal protocol; CFCs and HCFCs will prohibited soon, and cyclopentane will be play a key role in the polyurethane foam applications.

Safety notice
Cyclopentane is ignitable and explosive, so it should be kept far from heat, fire, oxidant and chemical reactant. It should be kept in shady, cool, dry and well ventilated place. when transport, load and unload should be carefully and prevent vibration of the container. When delivery in the pipe, static electricity should be in grounding. Don,t swallow it when operation, and avoid steam absorbing and touch into eye, skin and clothes.

It should be noted that n-pentane and isopentane have lower bioling point temperature than cyclopentane, please pay attention to the safety notice of cyclopentane.
