Low-crystallinity copolymer modifies polyethylene (PE) and polypropylene (PP) offering softness, improved impact resistance and lower melting point.
The TAFMER™ family of polyolefin elastomers is comprised of versatile copolymers that offer chemists and engineers more freedom to tailor polyethylene, polypropylene, EPDM, and polyamide compounds with unique properties. Owing to its low density, TAFMER™ is preferred by compounders who need to formulate the lowest cost solution for their customers. TAFMER™ is widely used in automotive thermoplastic polyolefin (TPO) compounds, wire & cable materials and packaging applications.
The polymer backbone of TAFMER™ is polyolefin based. Many grades are FDA compliant, and are supplied in talc-free form for immediate use in packaging film intended for food or aqueous containment. TAFMER™ is considered a most versatile polyolefin elastomer by formulators who are able to select the precise physical property balance they need, from a full menu of copolymers.
The TAFMER™ product family includes:
TAFMER™ A, DF | Ethylene- Butene copolymers | TAFMER™ A offers “fish eye” and heat seal initiation temperature (HSIT) control in transparent films. TAFMER™ DF offers excellent value in use. |
---|---|---|
TAFMER™ BL | Butene-Ethylene and Butene-Propylene copolymers | TAFMER™ BL offers peal strength control in packaging applications. TAFMER BL2400 Series offers low HSIT in PP films. |
TAFMER™ H | Ethylene-Octene copolymer | TAFMER™ H offers higer tensile strength over TAFMER™ DF |
TAFMER™ M | Acid Modified TAFMER™ | TAFMER™ M offers utility as a low cost impact modifier for polyamides. |
TAFMER™ P | Ethylene-Propylene copolymer | TAFMER™ P offers improved clarity in polyethylene films vs. TAFMER™A or DF. |
TAFMER™ PN | Propylene based Elastomer with nano-crystal structure | TAFMER™ PN offers improved clarity and impact resistance in polypropylene applications. |
TAFMER™ XM | Propylene-Butene copolymer | TAFMER™ XM offers an outstanding balance of HSIT and coefficient of friction (COF) for polypropylene sealant applications. |
An exciting innovation, TAFMER™ M is an acid modified elastomer. TAFMER™ M may be used to modify engineering plastics. As a function of pressure, heat and time, acid modified TAFMER™ M reacts with polymers that contain a RCONR2 amide functional group, a ROH hydroxyl functional group, or a RCOOR’ ester functional group, to improve room temperature and low temperature impact resistance when blending, or bonding to plastics containing these functional groups.
TAFMER™ PN offers a unique balance of softness and the heat resistance. TAFMER™ PN is a propylene based elastomer with controlled nano crystalline elements that add remarkable high heat resistance to this very soft material. The crystalline elements are finely dispersed in an amorphous matrix, which ensures excellent transparency. TAFMER™ PN offers Shore A 70-84 and a melting point of 140 to 160°C.
TAFMER™ polyolefin elastomer is a low-crystallinity alpha-olefin copolymer that features softness, low melting point, and compatibility with polyethylene (PE) and polypropylene (PP). When TAFMER™ is used to modify either PE or PP, the degree of compatibility may be selected to tailor the morphology of the compound. The resultant shift in physical properties is engineered to meet the requirements of the application.
Specific grades of TAFMER™ provide varying levels of compatibility in PE. The morphology of the polyethylene compound dictates its physical properties, and may be tailored to meet the needs of your specific application.
TAFMER™ grades offer varying levels of compatibility in PP. The morphology of the polypropylene compound dictates its physical properties, and may be tailored to meet the needs of your specific application.
TAFMER™ XM is highly miscible in PP. In packaging film applications, the benefits of enhancing PP with TAFMER™ are:
TAFMER™ PN is a newly launched series with finely dispersed crystalline structures in an amorphous matrix. The crystalline structures provide remarkably high heat resistance, yet the material retains outstanding softness. Because these crystalline structures are finely dispersed in an amorphous matrix, TAFMER™ PN offers excellent transparency and reduced stress whitening of polypropylene film.
In Wire & Cable applications, the miscibility TAFMER™ allows it to function as plasticizer of polypropylene, without sacrificing scratch and abrasion resistance.
In general injection molding applications, the miscibility TAFMER™ PN in PP offer a great advantage in applications requiring both transparency and impact resistance. In addition, PP modified with TAFMER™ PN exhibits improved hinge strength and reduced stress whitening.
TAFMER™ M offers cost effective impact modification of polyamide “nylon” resins.
When used as a resin modifier, TAFMER™ dramatically improves the performance of PE, PP, and other thermoplastics in automotive, wire and cable, as well as packaging applications.
TAFMER™ is widely used in automotive, industrial, and packaging applications, and may be processed by:
