HEPA/DOP/ASHRAE Panel Filters | Donaldson Industrial Dust
Higher filtration efficiency: 99.97% on 0.3 micron particles (emits three-0.3 micron particles per 10,000 particles) Exhaust airstream is near breathing zone. Lighter loading applications. Visible emissions are unacceptable. Customer specified HEPA level filtration.
TDA-5A & 5B Comparison of DOP Substitutes – ATI | Knowledge
DOP/DEHP: 750-760F: 5 psig: 10-11 lpm: 60% with metering valve fully open: Aerosol stream stable, uniform and dry. Output remained stable and dry while varying the concentration across operating range: DOS/DEHS: 780-790F: 4.75 psig: 6 lpm: 75%: Aerosol stream dry and uniform. Clogging of the heater block occurred due to increased block
Respirator Filter Efficiency Comparison of Dioctyl Phthalate
The investigation was conducted to obtain baseline data for DOP to be used as a comparison in future investigations which evaluate the filter efficiency characteristics of potential nontoxic DOP replacement aerosol challenge agents. The HE filters tested revealed filter efficiency greater than the minimum criteria set forth in 30 CFR Part 11.
/tardir/mig/a294503 - DTIC
Subsequently, ERDEC scientists recommended Emery 3004 as a general replacement for DOP, and interest among other users grew rapidly until, today, Emery 3004 is known to virtually all filter testers. Among these are the Department of Energy, and the pharmaceutical organization of Eli Lilly and Company.

But DOP is now considered two dozen candidate replacement materials that were to be a potentially hazardous material. The research tested, isostearic acid and oleic acid also performed reported here, which was performed using ATI Q-127 well as DOP replacements.
- Is DOP better than RoHS?
- RoHS also has the same limits. In Japan it is less than 0.05% or 500 ppm. It is therefore necessary to use its cost-effective replacement, as good as DOP, possibly better that DOP, without causing health problems. Besides, it should be able to accept secondary plasticizer CP, without health hazard.
- Is DOP better than DINP?
- DINP offers superior resistance to volatility, cost wise it is similar to cost of DOP, making it a frequently-selected effective and efficient alternative to DOP. Introduction: DOP, also known as DEHP or DnOP is traditionally used as a general-purpose plasticizer, satisfying wide range of requirements.
- Is DOP a good plasticizer?
- Plasticizing efficiency of DOP is considered as “1” and efficiency all other plasticizers is evaluated with reference to DOP. Besides, cost of DOP based compound can be reduced by blending it with CPW of appropriate grade in appropriate proportion (70:30), without affecting quality of product. However, DOP is on its way out due to health concerns.
- What are the new requirements for DOP?
- REACH requirements for DOP: The latest amendments now require all types of products containing the plasticizers BBP, DBP, DEHP, and DIBP to meet the requirements limiting the quantity of restricted phthalates in any item to less than 0.1% (1000 ppm) of the entire article’s composition.
- Is MCCP a good replacement for DOP?
- Interestingly MCCP is accepted by REACH specifications. MCCP with 52% chlorine is good. One such replacement is citrate-based plasticizer, but experience is that when CP is blended with it at the same level as in DOP, the CP migrates to the surface of product in due course.
- How to reduce cost of DOP based compound?
- Besides, cost of DOP based compound can be reduced by blending it with CPW of appropriate grade in appropriate proportion (70:30), without affecting quality of product. However, DOP is on its way out due to health concerns. REACH requirements for DOP:
