1. TRUVISION POLYMERS
DROPPER ASSEMBLIES
1

2. DROPPER ASSEMBLY :
• DROPPER ASSEMBLIES CONSIST A SMALL TUBE
WITH A RUBBER BULB AT ONE END FOR
DRAWING MEDICINE AND RELEASING IT A DROP
AT A TIME.
• DROPPER ASSEMBLIES ARE USED TO
ADMINISTER MEDICATION FOR PEDIATRIC USE.
• THE RAW MATERIAL USED FOR
MANUFACTURING DROPPER ASSEMBLIES MUST
BE PURE AND SAFE FOR PEDIATRIC USE.

3. PARTS OF DROPPER ASSEMBLY
• MEASURING PIPETTE.
• POLYPROPYLENE CAPS.
• RUBBER TEAT.

4. TRUVISION POLYMERS
OUR DROPPER ASSEMBLIES
• MEASURING PIPETTE IS MADE OF VIRGIN
POLYSTYRENE AND IS GRADUATED TO MEASURE
0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9 & 1.0 ML.
• CAP IS MADE OF VIRGIN POLYPROPYLENE AND IS
AVAILABLE IN TWO SIZES NAMELY 22MM & 25
MM.
• OUR TEATS ARE REPLACEMENT FOR THE
NATURAL RUBBER TEATS. OUR TEATS ARE MADE
OF THERMOPLASTIC ELASTOMER (TPE).

5. THERMOPLASTIC ELASTOMER
• TPE ARE UNIQUE BLENDS OF STYRENIC TRI-BLOCK
COPOLYMER RUBBER AND
THERMOPLASTIC RESINS FORMULATED TO YIELD
A BROAD ARRAY OF HARDNESS, TEXTURE,AND
PHYSICAL PROPERTIES.TPE’S HIGH ELASTICITY
AND TENSILE STRENGHT MAKE IT IDEAL FOR
APPLICATIONS REQUIRING RUBBER LIKE
CHARACTERSTICS. VERSATILE FORMULATIONS
ALLOW PROCESSING EITHER BY INJECTION
MOLDING,EXTRUSION OR BLOW MOLDING
5

6. MATERIAL CHARACTERSTICS OF TPE
• SUPERIOR ELASTICITY
• HIGH TENSILE STRENGTH AT LOW HARDNESS
• SKIN OIL RESISTANT
• EASILY COLORED
• BONDABLE TO POLYOLEFIN’S
• FDA COMPLAINTS
• ODORLESS
• RECYCLABLE AND REPROCESSABLE
• EXCEPTIONAL LOW TEMPRATURE PROPERTIES
• STABLE AT ELEVATED TEMPERATURES
• EXCELLENT UV STABILITY
• RESISTANT TO ACIDS, BASES, AND ALCOHOLS
• FREE OF PVC AND LATEX
• STERILIZED EITHER ETO AN D STEAM
• LOW EXTRACTABLE

7. FACTORS DRIVING MOVE TO REPLACE
THERMOSET RUBBERS WITH TPE’S
1. PROCESSIBILITY AND DESIGN FLEXIBILITY OF
TPE’S
2. CLEANLINESS OF TPE’S (LOW EXTRACTABLES)
3. MATERIAL COST
• ANY ONE OR A COMBINATION OF THESE THREE
FACTORS CAN LEAD TO OVERALL COST
REDUCTION FOR THE PRODUCT OR TO A
MARKETPLACE ADVANTAGE OVER TRADITIONAL
THERMOSET (RUBBER) PRODUCTS
7

8. PROCESSING OF TPE’S
• AS TPE’S ARE THERMOPLASTIC, THEY CAN BE PROCESSED ON
ANY TYPE OF EQUIPMENT THAT CAN HANDLE
THERMOPLASTIC MATERIALS INCLUDING STANDARD
INJECTION MOLDING MACHINES AND EXTRUSION
EQUIPMENT.
• THERMOSET RUBBER REQUIRE SPECIAL VULCANIZING
EQUIPMENTS AND CANNOT BE HANDLED BY PERSONNEL
FAMILIAR ONLY WITH THERMOPLASTIC ENGINEERING
TECHNOLOGY
• SO MEDICAL PRODUCT MANUFACTURERS GENERALLY BUY
THERMOSET RUBBER PARTS FROM OUTSIDE VENDORS
WHICH IMPLIES LOSS OF MANUFACTURING AND COST
CONTROL

9. ADVANTAGES OF TPE OVER LATEX
LATEX RUBBER
• FABRICATION OF RUBBER TAKES
SEVERAL MINUTES
• SCRAP GENERATED IS VERY HIGH
AND IT IS NOT REUSABLE
• MANY CURING AGENTS LIKE
SULPHUR(HIGHLY TOXIC),
NITROSAMINES(KNOWN
CARCINOGEN) ,PEROXIDES
REQUIRED TO BE ADDED TO GUM
RUBBER TO ASSIST
CROSSLINKING OF RUBBER TO
PROVIDE DESIRED ENGINEERING
PROPERTIES TO THE THERMOSET
RUBBER
• CONTINUE …..
TPE
• FABRICATION IS IN RAPID (IN
SECONDS)
• SCRAP GENERATED IS
COMPLETELY RECYCLABLE THUS
PROTECTS OUR ENVIORNMENT
(GREEN)
• NO CURING AGENTS REQUIRED.

10. ADVANTAGES OF TPE OVER LATEX
LATEX RUBBER
• SPECIFIC GRAVITY OF LATEX
RUBBER IS BETWEEN 1-1.35
THIS IS BECAUSE OF THE
ADDITIVES AND FILLERS
WHICH ARE ADDED TO THE
GUM RUBBER TO DECREASE
THE COST OF THE RAW
MATERIAL WHICH IN TURN
ADDS TO THE TOXCICITY OF
THE PRODUCT AND GIVE
LOW YIELD (LESS NO OF
PARTS PER KG OF RUBBER)
TPE
• SPECIFIC GRAVITY OF TPE IS
LESS THAN 1 ,THIS IS
BECAUSE VERY LESS OR NO
ADDITIVES ARE ADDED TO
THE POLYMER THUS
MAKING IT VERY PURE AND
SAFE MATERIAL FOR USE IN
MEDICAL APPLICATIONS .
THE YIELD IS ALSO MORE
THAN RUBBER THUS
MAKING IT ECONOMICAL
TO USE. 10

11. ADVANTAGES OF TPE OVER LATEX
LATEX RUBBER
• NUMEROUS CHEMICAL ADDITIVES,
VULCANZAITES, AND FILLERS MUST BE
ADDED TO GUM RUBBER MATRICES FOR
THE PURPOSE OF CROSSLINKING THE
RUBBER AND OR TO PROVIDE DESIRED
ENGNEERING PROPERTIES TO THE
THERMOSET RUBBER. THESE CATALYSTS
AND PROCESSING AIDS GIVE RISE TO
MAJOR PROBLEM OFTEN ENCOUNTERED
IN BIOMEDICAL APPLICATIONS OF
THERMOSET RUBBERS. THEREFORE
WASHING STEPS ARE NORMALLY USED BY
MEDICAL INDUSTRY TO REMOVE
/EXTRACT SURFACE RESIDUALS FROM THE
THERMOSET RUBBERS, THUS REDUCING
THE TOXICITY OF THESE MATERIALS TO
ACCEPTABLE LEVELS. SUCH CLEANING
AND EXTRACTION PROCESSES ADD A
SUBSTANTIAL COST TO RUBBER PARTS.
TPE
• THE CLEANLINESS OF THERMOPLASTIC
ELASTOMERS ,FROM THE STANDPOINT OF
TOXICITY AND EXTRACTABLES, OFTEN
MAKES THEM SUPERIOR MATERIALS FOR
USE IN MEDICAL PRODUCTS. IT IS NOT
NECESSARY TO WASH TPE PARTS AFTER
FABRICATION AS THEY GENERALLY WILL
PASS THE REQUIRED TOXICITY TESTS.
11

12. ADVANTAGES OF
TPE OVER LATEX
THERMOSET RUBBER
FABRICATION INVOLVES
NUMEROUS CONTROL AND
PROCESSING STEPS . EVERY STEPS
IN A MEDICAL MANUFACTURING
ENVIORNMENT WOULD HAVE
TO BE MONITORED , ADDING TO
THE COST OF THE
MANUFACTURING PROCESS
THESE STEPS ARE NOT REQUIRED
IN FABRICATION OF PARTS FROM
TPE AS IS EVIDENT FROM THE
SHOWN DIAGRAM .
