INDUSTRY SPECIFIC TERMINOLOGY

EPDM Rubber
Thermo Plastic Olefin
PVC Roofing Membrane
Spray Foam Roofing

EPDM Rubber

EPDM rubber (ethylene propylene diene monomer rubber) is an elastomer which is characterized by wide range of applications. The diene(s) currently used in the manufacture of EPDM rubbers are DCPD (dicyclopentadiene), ENB (ethylidene norbornene) and VNB (vinyl norbornene).

EPDM rubber is used in vibrators and seals; glass-run channel; radiator, garden and appliance hose; tubing; washers; belts; and electrical insulation. It is also used as a medium for water resistance in high-voltage polymeric cable jointing installations, roofing membrane, geomembranes, rubber mechanical goods, plastic impact modification, thermoplastic, vulcanizates, as a motor oil additive, pond liner, electrical cable-jointing and chainmail applications.

EPDM exhibits satisfactory compatibility with fireproof hydraulic fluids, ketones, hot and cold water, and alkalis, and unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons, halogenated solvents, and concentrated acids.

Typical properties of EPDM vulcanisates are given below. EPDM can be compounded to meet specific properties to a limit depending first on the EPDM polymers available, then the processing and curing method(s) employed. EPDMs are available in a range of molecular weights (indicated in terms of Mooney viscosity ML(1+4)@125°C), varying levels of ethylene, third monomer and oil content.

Mechanical Properties 
Hardness, Shore A 40 - 90 
Tensile Strength, Ultimate 25 MPa 
Density Can be compounded from 0.90 to >2.00 gcm-³ 
Abrasion resistance 450 mm3 
Thermal Properties 
CTE, linear 68°F 576 µm/m-°C 
Maximum Service Temperature, Air 150 °C 
Minimum Service Temperature, Air -54 °C 
Glass Temperature -54 °C 


Common Application
EPDM rubber is commonly used in weatherseals on all vehicles. This includes door seals, window seals, trunk seals, and sometimes hood seals. Frequently these seals are the source of noise due to movement of the door versus the car body. This is due to friction between the EPDM rubber and the mating surface (car painted sheet metal or glass). This can be alleviated using specialty coatings that are applied at the time of manufacture of the weatherseal, not as an aftermarket application. Such coatings can also greatly increase the chemical resistance of EPDM rubber. Some vehicle manufacturers such as General Motors also recommend a light application of silicone dielectric grease to weatherstripping to reduce noise.

Thermo Plastic Olefin

ThermoPlastic Olefin (TPO) is a trade name that refers to polymer/filler blends usually consisting of some fraction of PP (polypropylene), PE (polyethylene), BCPP (block copolymer polypropylene), rubber, and a reinforcing filler. Common fillers include, though are not restricted to talc, fiberglass, carbon fiber, wollastonite, and MOS(Metal Oxy Sulfate). 

Common rubbers include EPR (ethylene-propylene rubber), EPDM (EP-diene rubber), EO (ethylene-octene), EB (ethylene-butadiene), SEBS (Styrene-ethylene-butadiene-styrene). Currently there is a great variety of commercially available rubbers and BCPP's. They are produced using regioselective and stereoselective catalysts known as metallocenes. The metallocene catalyst becomes embedded in the polymer and cannot be recovered.

The geometry of the metallocene catalyst will determine the sequence of chirality in the chain, as in, atactic, syndiotactic, isotactic, as well as average block length, molecular weight and distribution. These characteristics will in turn govern the microstructure of the blend.

The components are blended together at 210 - 270 °C under high shear. A twin screw extruder or a continuous mixer may be employed to achieve a continuous stream, or a Banbury® compounder may be employed for batch production. A higher degree of mixing and dispersion is achieved in the batch process, but the superheat batch must immediately be processed through an extruder to be pelletized into a transportable intermediate. Thus batch production essentially adds an additional cost step.

As in metal alloys the properties of a TPO product depend greatly upon controlling the size and distribution of the microstructure. PP and PE form a vaguely crystalline structure known as a spherulite. Unlike metals, a spherulite cannot be described in terms of a lattice or unit cell, but rather as a set of polymer chains that pack down closely next to one another and form a dense core. The PP and PE components of a blend constitute the "crystalline phase", and the rubber gives the "amorphous phase".

If PP and PE are the dominant component of a TPO blend then the rubber fraction will be dispersed into a continuous matrix of "crystalline" polypropylene. If the fraction of rubber is greater than 40% phase inversion may be possible when the blend cools, resulting in an amorphous continuous phase, and a crystalline dispersed phase. This type of material is non-rigid, and is sometimes called TPR for ThermoPlastic Rubber.

To increase the rigidity of a TPO blend, fillers exploit a surface tension phenomena. By selecting a filler with a higher surface area per weight, we can achieve a higher flexural modulus.

TPO blends have densities 0.92 - 1.1

TPO is frequently found in outdoor applications such as roofing because it does not degrade under solar UV radiation, a common problem with nylons. TPO is used extensively in the automotive industry.

TPO is easily processed by injection molding, profile extrusion, and thermoforming. TPO cannot be blown, or sustain a film thickness less than 1/4 mil (about 6 micrometres), where 1 mil is equal to 0.001 inch.

PVC Roofing Membrane

Description: 
PVC membranes are grease resistant, which makes them an ideal choice for commercial buildings such as restaurants and apartments where cooking residue is discharged through vents on the roof. PVC membrane is reinforced with fabric, which provides increased strength and stability. 

Life Expectancy: 
Unavailable 

Maintenance/Installation/Concerns: 
Have been known to become brittle over time. 

Spray Foam Roofing
SPF is sprayed polyurethane foam, a closed cell roofing and insulation material that is rapidly gaining market share in today’s construction industry. Because it is spray applied, it forms a seamless barrier to the weather. 

They can be applied to vertical surfaces such as parapet walls thus eliminating seams and cold joints (the main source of roof leaks). SPF has no fasteners. Fasteners puncture decks, contributing to premature failure, create thermal bridging, reducing insulation value and tend to pull-out under wind load. 

Life Expectancy: 
Unavailable 

Maintenance/Installation/Concerns: 
Though many SPF roofs exist today after installation over 20 years ago, it is still considered a new technology and, as such, is accompanied by misunderstandings regarding the proper utilization of the product. Improper material selection, design, or installation could result in the type of roof failures associated with conventional roofing systems.
