Joinville
Also known as the City of Flowers, has a population around
500.000 inhabitants (Santa Catarina has about 5.5 million
people) and one of the highest incomes per capita in the
country - around US$ 6.500,00/year.
Joinville is a city with a "European air", which can be
observed by the buildings and customs - inherited from its
German colonization.
7
Joinville
It is the largest and richest city in the State of Santa Catarina
GDP of Santa Catarina is equal (U$ 50 billions) the sum of
the GDP of Bolivia, Paraguai and Uruguai.
It has the largest industrial site in the State - the third largest
in south of Brasil.
The city has about 2.546 industries operating in the following
sectors: metal-mechanics, textiles, ready-made articles,
plastics, rubber, foods and chemicals.

UDESC - Joinville
The Center for Technological Sciences is part of the Santa Catarina
State University, a public institution founded in 1965, and offers
undergraduate and graduate engineering courses.
The main research areas are superplasticity, metallic alloys, powder
metalurgy, advanced ceramics, composites, biomaterials, modelling
and simulation and polymer materials and processing.
We also have a graduate course in Physics and Electrical
Engineering.
UDESC-Joinville has about 170 faculties, 2500 students and 70
graduate students.

- semi-cristalino (%Cristalinidade de até 70%)
- Tm = 170 a 180ºC
- Tg = 0 a 5ºC
- frágil
- baixo alongamento (< 10%) e resistência ao impacto (≅ 30 J/m)
- elevado módulo de elasticidade (≅ 3,8 GPa)
- elevada tensão na ruptura (≅ 35 MPa)

- copolímero randômico com unidades 3HV
- variação da quantidade de 3HV → alteração de propriedades
- em relação ao P(3HB):
- menor cristalinidade
- menor Tm e Tg
- menor módulo, maior alongamento
- melhor resistência ao impacto
