HOUSTON, Aug. 5 /EMWNews/ -- Texas Petrochemicals Inc.

(TPC), (OTC: TXPI.PK), a Houston based petrochemical company that provides

a diverse range of quality products and services into performance,

specialty and intermediate manufacturing markets worldwide, today announced

a price increase on its polyisobutylene product line.



    Effective September 1, 2008, TPC will raise polyisobutylene pricing by

up to 12 percent, depending on grade, and make adjustments to off-list

pricing as contracts allow. These changes are driven by the recent rapid

increase in isobutane feedstock and natural gas costs.



    "The sustained high prices for hydrocarbon based raw materials continue

to adversely impact our business, requiring TPC to implement an increase at

this time," said Vice President and General Manager for Performance

Products Sandra Davis. "We are focused on maintaining a viable PIB business

that can supply our customers over the long term. TPC plans to begin

commissioning its new plant in August and expects to startup in the fourth

quarter, effectively doubling the capacity once on-line."



    TPC first entered the PIB market in May 2000 with the startup of its

patented process to manufacture both highly reactive and enhanced PIB

products. Since that time, the company has more than doubled its original

capacity through multiple expansion projects.



    TPC manufactures polyisobutylene at its Houston plant, making a

complete line of high-quality polyisobutylene products ranging in molecular

weight from 350 to 3500. The company also manufactures highly reactive

polyisobutylene products ranging in molecular weight from 350 to 2300 which

are valued for production of fuel and lubrication oil dispersant products.

TPC sells its products worldwide directly to customers or through several

break-bulk distributors.



    Headquartered in Houston, Texas, Texas Petrochemicals Inc. is a premier

chemical company with more than $2 billion in annual sales. Its products

are sold to a wide range of performance, specialty and intermediate

markets, including synthetic rubber, fuel additives, plastics and

detergents. The Company has manufacturing facilities in the industrial

corridor adjacent to the Houston Ship Channel, Port Neches and Baytown,

Texas and operates a product terminal in Lake Charles, Louisiana. For more
