Perovion TEPO L30 is a liquid organic peroxide formulation based on 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-trioxonane, a cyclic ketone peroxide supplied as a 30% active solution for continuous metering into polymer processing lines. Perovion TEPO L30 is engineered to give processors precise, repeatable control over molecular weight reduction in polypropylene and to serve as a high-temperature initiator for polyolefin and (meth)acrylate polymerization systems, supporting the tight melt flow index tolerances that downstream fiber and nonwoven converters increasingly demand.
Overview
Perovion TEPO L30 belongs to the cyclic ketone peroxide family and is chemically identical in active content to well-known controlled-rheology polypropylene (CR-PP) initiators, but is supplied as a 30% liquid solution rather than a solid masterbatch. This liquid format allows processors who operate continuous extrusion lines with liquid dosing pumps to introduce the peroxide directly into the melt stream without the handling steps associated with solid carrier pellets, which in turn shortens changeover time between production grades and reduces the risk of cross-contamination from residual masterbatch carrier resin.
Because Perovion TEPO L30 decomposes at a controlled rate under extrusion temperatures, it generates a defined population of free radicals that selectively cleave polypropylene chains, narrowing the molecular weight distribution and raising melt flow index in a predictable, repeatable manner across production batches. This consistency is particularly valued by converters running high-speed spunbond and meltblown lines, where even small MFI swings can disrupt fiber diameter and line speed.
Key Features
- 30% active liquid solution suitable for continuous pump-fed dosing systems
- Controlled, repeatable molecular weight reduction for CR-PP visbreaking
- Compatible with high-temperature LDPE polymerization processes
- Effective initiator for (meth)acrylate and related monomer polymerization
- Liquid format reduces dust and handling exposure versus solid masterbatch grades
Typical Applications
The primary application of Perovion TEPO L30 is controlled rheology polypropylene production, where converters need a precise, high melt flow index resin for fiber spinning, nonwoven fabrication, or injection molding of thin-wall parts. Metering the liquid peroxide directly into the extruder feed throat or barrel gives operators finer dosing resolution than pellet-form masterbatches, which is valuable when producing narrow MFI specification grades, and it also simplifies scale-up between pilot and full production lines since dosing rates can be adjusted continuously rather than through discrete masterbatch letdown ratios.
Beyond CR-PP, Perovion TEPO L30 also functions as a high-temperature initiator in LDPE autoclave and tubular polymerization processes, and as an initiator for solution or bulk polymerization of acrylate and methacrylate monomers used in coatings, adhesives, and specialty resin formulations. In each of these applications, the liquid format of Perovion TEPO L30 allows formulators to blend it directly into monomer feed streams at the point of use.

Thermal Stability
Perovion TEPO L30 has a decomposition profile consistent with cyclic ketone peroxides, which begin generating radicals at moderate extrusion temperatures and reach practical half-life decomposition rates in the ranges typically used for CR-PP visbreaking and high-temperature polyolefin polymerization. Processors typically select a screw speed and barrel temperature profile that allows sufficient residence time for the peroxide to fully decompose before the melt exits the die, ensuring consistent chain scission across the full cross-section of the extrudate.
Exact self-accelerating decomposition temperature (SADT) and one-hour half-life temperature values are to be confirmed based on the final specification sheet, but processors should follow the same conservative handling temperature margins used for other cyclic peroxide initiators, and should avoid prolonged holding of the liquid at elevated ambient temperatures prior to use.
Storage Recommendations
Perovion TEPO L30 should be stored in tightly closed original containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. As with other liquid organic peroxides, storage above the minimum recommended temperature threshold helps prevent crystallization or phase separation of the active ingredient from the carrier, while storage below the maximum recommended temperature limits premature decomposition. Facilities should also rotate stock on a first-in, first-out basis and avoid storing Perovion TEPO L30 near sources of heat, open flame, or strong oxidizing agents. Specific minimum and maximum storage temperatures and shelf life are to be confirmed based on the final specification sheet.
Packaging & Transport
Perovion TEPO L30 is classified as an organic peroxide for transport purposes and must be shipped under the applicable UN organic peroxide entry with temperature control where required by the type classification. Customers receiving Perovion TEPO L30 should confirm local transport and storage regulations with their logistics provider before scheduling delivery, and should verify that receiving warehouse conditions match the storage requirements noted on the product label and Safety Data Sheet. Exact UN number, packing group, and temperature control classification are to be confirmed based on the final specification sheet.
Standard packaging formats for liquid organic peroxides of this type include HDPE drums or smaller HDPE containers sized to limit single-package quantity in line with regulatory thresholds, and shipments should be accompanied by the current Safety Data Sheet and any required organic peroxide transport documentation.
Safety & Handling
Perovion TEPO L30 should be handled in accordance with applicable safety procedures for organic peroxides. The product is classified as an oxidizing and potentially hazardous material and requires appropriate storage and handling measures, including keeping it segregated from reducing agents, accelerators, acids, and other incompatible substances.
Operators should review the Safety Data Sheet before handling Perovion TEPO L30, and should wear appropriate personal protective equipment including chemical-resistant gloves and eye protection when transferring or dosing the liquid, and should ensure metering pumps and transfer lines are rated for compatibility with organic peroxide chemistries.
