用途：

1．乙烯聚合引發(fā)劑

TMHP是一種常用的LDPE管式法或釜式法聚合引發(fā)劑，為了獲取更廣的聚合溫度范圍，常常和其它引發(fā)劑配合使用，聚合溫度為150-190℃。

2．氯乙烯聚合引發(fā)劑

TMHP也是水相懸浮法氯乙烯聚合的引發(fā)劑，引發(fā)溫度為50-70℃。 

貯存條件：

保持包裝密閉并處于良好通風(fēng)狀態(tài)下，max貯存溫度為0℃，避免和還原劑如胺類、酸、堿、重金屬化合物（促進(jìn)劑及金屬皂），嚴(yán)禁在庫房?jī)?nèi)分裝及取用。

貯存穩(wěn)定性：

按廠家提示的條件進(jìn)行保存，產(chǎn)品在三個(gè)月內(nèi)可保證出廠技術(shù)標(biāo)準(zhǔn)。

滅火：

小的火災(zāi)需用干粉或二氧化碳滅火器滅火，同時(shí)用大量水噴灑，防止再燃。大火需在安全距離之外用大量水噴射。

(3) Please refer to the Safety Data Sheet (MSDS) of this product.

Purpose:

1. Ethylene polymerization initiator

TMHP is the most commonly used LDPE tubular or kettle polymerization initiator. In order to obtain a wider polymerization temperature range, it is often used in conjunction with other initiators, with a polymerization temperature of 150-190 ℃.

2. Vinyl chloride polymerization initiator

TMHP is also an initiator for the aqueous suspension polymerization of vinyl chloride, with an initiation temperature of 50-70 ℃.

Storage conditions:

Keep the packaging sealed and in a well ventilated state, with a maximum storage temperature of 0 ℃. Avoid mixing with reducing agents such as amines, acids, alkalis, and heavy metal compounds (accelerators and metal soaps). It is strictly prohibited to pack or use in the warehouse.

Storage stability:

Store according to the manufacturer's instructions, and the product can meet the factory technical standards within three months.

Fire extinguishing:

Small fires need to be extinguished with dry powder or carbon dioxide fire extinguishers, and a large amount of water should be sprayed to prevent reignition. A large fire requires spraying a large amount of water from a safe distance.
