Applications

Polymerization of ethylene

• LQ-K is an efficient initiator for the ethylene polymerization under high pressure in both  autoclave and tubular processes. To obtain a wide spectrum of polymerization temperatures, combinations with other peroxides are applied in practice. Depending on reaction conditions. LQ-K is active in the temperature range of 150-190℃. 

Polymerization of vinylchloride

• LQ-K is used as an initiator for the suspension and mass polymerization of vinylchloride between 50℃ and 70℃.

Technical Details & Test Data

Half Life Data

The reactivity of an organic peroxide is usually given by its half life (t1/2) at various temperatures. For LQ-K in chlorobenzene:

• t at 0.1 hr = 96℃
• t at 1 hr = 77℃
• t at10 hr = 59℃

Main Decomposition Product

Carbon dioxide, 2,2,4,7,9,9-hexamethyldecane, 2,4,4-Trimethylpentane

Packaging & Availability

Packing and Transportation

• The standard packaging is a 25-liter HDPE can for 20 kg peroxide solution. Both packaging and transport meet the international regulations. 
• LQ-K is classified as Organic peroxide type D, liquid, temperature controlled; Division 5.2; UN 3115; PG II.
• Rail (RID) and air (ICAO-TI/IATA-DGR) transport are forbidden.

Storage & Handling

Storage

LQ-K Ts max. = 0℃ and Ts min. = -10℃ to prevent crystallization. When stored according to these recommended storage conditions, LQ-K will remain within our plant specifications for a period of at least three months after delivery.
