EPDM ULD Sponge Requirements -an illustration of our AD programs Density < 0.1 (If possible to match NBR/PVC density 0.08 to 0.06) Closed cell for insulation applications Good outer skin formation Good extrusion properties Continuous hot air cure Flame resistant systems now also available
The Challenge With such poor uncured strength, how is it possible to make ultra low density sponge from EPDM? Answers: 1. Increase the compound strength at the time of blowing agent decomposition to resist cell rupture. 2. Improve the compounds ability to contain high volumes of gas by raising the gas retention efficiency (GRE). Note: Understanding the challenge is easy. Achieving it is difficult. a. Polymer? b. Cure system? c. Process set-up?
Desired Outcome Achieved Correct polymer and ingredient choice has resulted in high gas retention efficiency. Densities of less than 0.06g/cm³ have been achieved. High GRE has resulted in significantly lower blowing agent additions for EPDM ULD sponge compared to NBR/PVC. EPDM ultra low density sponge can be produced on standard production facilities.
Keltan Reactive Extrusion Development EPM is reacted with Peroxides and Maleic Anhydride in a continuous extrusion operation (hence Reactive Extrusion) Petroleum Additives Wood-Plastic Composites Nylon impact modification etc,. Plant was opened mid-2008 in Triunfo, Brazil Product Form Bales Pellets Some illustrations of applications
Dispersant Viscosity Index Improvers Increased environmental restrictions on diesel emissions have resulted in a redesign of the engine to include exhaust gas recirculation. For diesel engines this has the effect of dumping a bag of coal in the crankcase. The result is greatly shortened oil change intervals leading to increased operating costs. DSM functionalized polymers are used to make dispersant viscosity index improvers that handle the increased soot and restore the normal oil change interval for HDD-EGR engines. This helps operating costs and contributes to a cleaner environment.

Polyamide Impact Modification DE5005 Impact resistance is the property of a material to absorb the energy of a sudden shock Some materials such as rubbers have very high impact strength, whereas many high performance materials have low impact resistance which is often observed in form of brittleness at low or ambient temperature Many engineering thermoplastics can be impact modified by adding a dispersion of soft, rubbery particles to the rigid EP matrix SAN, PC, PS, PA, PBT all have impact modified versions commercialized n-charpy [kj/m²] 60 Impact strength 50 40 Brittle/tough 30 transition 20 10 PA6 Soft Rubber particle PA6/DE5005/Plastomer PA6 (literature) DE5005/Plastomer 0-25 -5 15 35 55 75 Temperature [ C] DE5005 is a highly functional non-crystalline polyolefin compatibiliser Impact PA6 compound 72% PA6 7% DE5005 21% Plastomer PA6 Suited for the impact modification of PA6 Allowing system cost reduction by dilution Introducing additional processing flexibility by a 2-component impact modifier system Increasing initial elongation at break Increasing notched impact energy Lowering the brittle/tough transition temperature
